"We, the artists, and Sacramento County all thought we had a shot at being the first post-COVID festival to happen. That really would have been incredible.

Forget The Hearse: AC/DC's 'Back In Black' Turns 40
 

Updated Friday Oct. 13, 2023 to include info about Kendrick Lamar's most recent GRAMMY wins, as of the 2023 GRAMMYs.

A GRAMMY veteran these days, Kendrick Lamar has won 17 GRAMMYs and has received 47 GRAMMY nominations overall. A sizable chunk of his trophies came from the 58th annual GRAMMY Awards in 2016, when he walked away with five — including his first-ever win in the Best Rap Album category.

This installment of GRAMMY Rewind turns back the clock to 2016, revisiting Lamar's acceptance speech upon winning Best Rap Album for To Pimp A Butterfly. Though Lamar was alone on stage, he made it clear that he wouldn't be at the top of his game without the help of a broad support system. 

"First off, all glory to God, that's for sure," he said, kicking off a speech that went on to thank his parents, who he described as his "those who gave me the responsibility of knowing, of accepting the good with the bad."

He also extended his love and gratitude to his fiancée, Whitney Alford, and shouted out his Top Dawg Entertainment labelmates. Lamar specifically praised Top Dawg's CEO, Anthony Tiffith, for finding and developing raw talent that might not otherwise get the chance to pursue their musical dreams.

"We'd never forget that: Taking these kids out of the projects, out of Compton, and putting them right here on this stage, to be the best that they can be," Lamar — a Compton native himself — continued, leading into an impassioned conclusion spotlighting some of the cornerstone rap albums that came before To Pimp a Butterfly.

"Hip-hop. Ice Cube. This is for hip-hop," he said. "This is for Snoop Dogg, Doggystyle. This is for Illmatic, this is for Nas. We will live forever. Believe that."

To Pimp a Butterfly singles "Alright" and "These Walls" earned Lamar three more GRAMMYs that night, the former winning Best Rap Performance and Best Rap Song and the latter taking Best Rap/Sung Collaboration (the song features Bilal, Anna Wise and Thundercat). He also won Best Music Video for the remix of Taylor Swift's "Bad Blood." 

Lamar has since won Best Rap Album two more times, taking home the golden gramophone in 2018 for his blockbuster LP DAMN., and in 2023 for his bold fifth album, Mr. Morale & the Big Steppers.

10 Essential Facts To Know About GRAMMY-Winning Rapper J. Cole

At first glance, the worlds of rock and dance music might appear diametrically opposed. Dig a little deeper, though, and the two genres share more than just a love for all-black outfits.

In recent years, a wave of dance stars have embraced their inner mosher by collaborating with their favorite metal, post-hardcore, emo, and pop-punk artists, creating a mutant sound with a foot in both spaces. Just this month, Canada's dark bass maestro Rezz released a winkingly titled EP, It's Not A Phase, which channels the punk and metal she loved as a teen. (On release day, she posted an old photo in front of a My Chemical Romance poster, with the caption, "this one's for everyone who had an emo phase.") 

The EP followed Illenium's self-titled album in April — which features several of the Denver producer's rock heroes — while the likes of Marshmello, Kayzo and Excision have also tried their hands at rock/dance collaborations. For DJ-producers who grew up on raw guitars and tear-the-house-down vocals, it's a natural next step. 

Of course, this mixing of worlds is not just a recent phenomenon. For decades, dance artists have remixed, borrowed from, and occasionally collaborated with their rock counterparts. From the punkish ferocity of the Prodigy's 1997 album The Fat of the Land to Justice's Slipknot-sampling "Genesis" ten years later, the examples are endless. 

In the decade since the EDM boom minted a new generation of superstars, crossover collaborations have increasingly positioned the dance artist in the lead. In honor of this phenomenon, we're head-banging our way through eight of the best. 

deadmau5 feat. Gerard Way — "Professional Griefers" (2012)

Back in 2012, as EDM was taking over America, deadmau5 was busy touring an early iteration of his eye-popping 'Cube' show and preparing to release his sixth studio album, > album title goes here <. Ahead of the LP, the producer born Joel Zimmerman released "Professional Griefers," a hard-charging dance-rock stomper featuring My Chemical Romance vocalist Gerard Way.

While fans had already heard an instrumental version of the track in deadmau5's live shows, Way's vampy vocals brought the rock swagger, even as the production remained resolutely electronic. To celebrate the release, the collaborators appeared as gamers piloting a UFC battle between two giant mau5-headed robots in what Zimmerman told SPIN was "one of the highest-budget electronic music videos of all time." And yes, it's as extra as it sounds. 

Steve Aoki feat. Fall Out Boy — "Back To Earth" (2014)

Steve Aoki is one of dance music's most voracious collaborators, teaming up with everyone from will.i.am to Louis Tomlinson to Backstreet Boys. He's also a punk rocker from way back, having jumped between hardcore bands as a singer and guitarist in his pre-fame life.

These passions have intersected throughout Aoki's DJ/producer career in his collaborations with Linkin Park and blink-182, as well as Rifoki, the straight-up hardcore band he formed with Sir Bob Cornelius Rifo of the Bloody Beetroots. 

In 2014, Aoki joined forces with pop-punk favorites Fall Out Boy on "Back To Earth," which featured on his collab-stacked album, Neon Future I. In an interview with Billboard, Aoki explained that the band worked on their live instrumentation in a separate studio before he added the dance elements, and the result was "one of my favorite rock collaborations." 

The Bloody Beetroots feat. Jason Butler — "Crash" (2017)

Like his friend and collaborator Steve Aoki, the Bloody Beetroots' masked leader Sir Bob Cornelius Rifo is a punk at heart. That raucous spirit was present on the breakout Aoki/Beetroots team-up, "Warp 1.9" (2009), then turned up to 11 in their aforementioned hardcore band, Rifoki.

In 2017, after a few years away from the limelight, Sir Rifo delivered the third Bloody Beetroots album, The Great Electronic Swindle, featuring guests like Jane's Addiction frontman Perry Farrell, GRAMMY-nominated singer-songwriter Greta Svabo Bech, and Australian rock band Jet. 

On "Crash," the Italian producer hooked up with post-hardcore singer Jason Butler, of Letlive and Fever 333, to make a heavy, distorted and shouty head-banger that honors both of their styles. In true punk fashion, it's over and out in just over two minutes. 

Kayzo & Underoath — "Wasted Space" (2018)

Few DJ-producers relish the opportunity to slam together dance music and rock quite like Houston-born Kayzo. For his 2019 album, Unleashed, the rising star secured some of his favorite metal, hardcore and pop-punk acts as guests, including Of Mice & Men, Boys of Fall, Blessthefall, and Alex Gaskarth of All Time Low.

One of the album's standouts, "Wasted Space," pairs Kayzo with Underoath, the Florida metalcore outfit who previously collaborated with Rezz on her 2019 release, "Falling." The collaboration is equal parts metal — with dueling vocalists Aaron Gillespie and Spencer Chamberlain at full-tilt — and shuddering bass drops built for an EDM main stage. 

Marshmello feat. A Day To Remember — "Rescue Me" (2019)

Perma-helmeted producer Marshmello has enjoyed a whirlwind decade, with a famously prolific output that includes several dance and pop hits. In 2019, he surprised fans by announcing a team-up with Florida four-piece A Day To Remember, whose metalcore meets pop-punk sound is a far cry from Marshmello's usual vibe.

Their collaboration, "Rescue Me," finds an easy middle ground between crunching rock guitars, frontman Jeremy McKinnon's impassioned vocals, and Marshmello's skittering trap-pop beats. In an interview with Kerrang! Radio, McKinnon recalled his surprise at how quickly Marshmello shared the chorus on socials, adding that he wishes rock artists could be as spontaneous. 

Illenium and All Time Low — "Back To You" (2023)

Hot on the heels of his first GRAMMY nomination in 2022, Denver-based phenom Illenium got back in the studio to make another album straight from the heart. The producer's self-titled fifth LP took inspiration from his teenage years listening to the likes of blink-182 and Linkin Park, while staying true to his own bass-heavy aesthetic.

Thanks to his stadium-filling stature, Illenium assembled a starry lineup of guests, including pop-punk royalty Avril Lavigne and Travis Barker on "Eyes Wide Shut" and metalcore band Motionless in White on "Nothing Ever After." Early fan favorite "Back To You" features the full force of pop-punkers All Time Low going up against Illenium's furious drops — and achieving perfect harmony. 

Excision, Wooli, and The Devil Wears Prada — "Reasons" (2023)

Fellow bass lovers Excision and Wooli are frequently paired, whether they're going back-to-back as DJs or co-producing EPs like 2019's Evolution and 2023's Titans. This time around, the collaborators decided to try something outside their comfort zone, calling up Ohioan metalcore band The Devil Wears Prada to bring their distinctive grit to "Reasons."

In contrast to more pop-leaning entries on this list, "Reasons" is unapologetically heavy from the halfway mark, morphing back-and-forth from metalcore theatrics to hard-hitting wubs. In a statement, The Devil Wears Prada described this team-up as "uncharted territory" for the band, and their gamble paid off. 

Rezz, Tim Henson, and Silverstein — "Dreamstate" (2023)

In a statement accompanying her new EP, It's Not A Phase, Rezz notes that she "grew up listening to bands exclusively, and over time developed an understanding of what it was about those songs that I loved." 

That innate grasp of rock dynamics is on full display throughout Rezz's most vocal-driven release to date, with guest turns from the likes of Alice Glass, Johnny Goth, and Raven Gray. On "Dreamstate," Rezz embraces her inner emo kid with the help of Canadian post-hardcore band Silverstein and metal guitar prodigy Tim Henson, undergirding her guests' contributions with dark, stabbing bass.

"I listened to a bunch of Silverstein growing up, so it felt nostalgic to me," Rezz told Front Row Live Ent., before admitting that it was "the hardest song I've ever mixed." The extra sweat resulted in a one-of-a-kind collaboration, proving once again that dance music and rock are a potent mix — one with plenty of fuel left in the tank.

Since its release in 2003, there's been a consistent (pingy) drumbeat of chatter about Metallica's St. Anger.

The quixotic snare sound — which bassist and producer Bob Rock claimed he spent about 15 minutes crafting — is central to the St. Anger discourse; a Google search for "metallica st. anger snare" yields about 661,000 results. As for why the eight-time GRAMMY winners uncharacteristically nixed guitar solos? That question yields millions of hits.

Then there's the 2004 documentary Some Kind of Monster, one of the most uncomfortably revealing portraits of a rock band engulfed in a mid-life crisis. Memorable moments abound, but for one scene alone — drummer Lars Ulrich's Middle Earth-looking dad hearing a take, and telling his son to "delete that" — the film is a must-watch.

Given the controversial status St. Anger has accrued, it may seem like the metal community may want to, well, delete it. While your mileage may vary, this hotly debated album shouldn't be consigned to any internet-snark dustbin.

Listening with the benefit of temporal distance, tracks like "Frantic," "Some Kind of Monster" and "The Unnamed Feeling" sound raw and alive — perhaps of their time, given its adjacency to then-ascendant nü metal. Ultimately, they conjure the sensation of a reset, rather than a capitulation to trends. 

Today, St. Anger seems to hew less to the reputation it's engineered, and more to Rock's characterization of the thing: "To me, this album sounds like four guys in a garage getting together and writing rock songs. There was really no time to get amazing performances out of James. We liked the raw performances… we just did it, boom, and that was it."

To mark the 20th anniversary of St. Anger, here are five facts about the album.

Metallica Started The Album In An Old Army Barracks

By 2001, Metallica hadn't released an album of original material in almost five years, since 1997's Reload (a follow-up to the previous year's Load). 

While these sessions ground to a halt due to personal upheaval and frontman James Hetfield heading to rehab — and the band later continued work at a new studio in San Rafael, California — this no-nonsense setting befitted the unvarnished quality of the music.

Bassist Jason Newsted Left The Band Early On

Newsted was the second bassist for Metallica, after the tragic 1986 death of Cliff Burton. Newsted's departure came the month they began St. Anger, which destabilized progress on the album.

"Due to private and personal reasons, and the physical damage that I have done to myself over the years while playing the music that I love, I must step away from the band," Newsted said in a statement. "This is the most difficult decision of my life, made in the best interest of my family, myself, and the continued growth of Metallica."

St. Anger Represented Intense Catharsis For James Hetfield

As Hetfield put it, St. Anger was a valve for which to release intense psychological pressure.

"There's a lot of passion in this. There's two years of condensed emotion in this," he told Metal Edge magazine at the time. "We've gone through a lot of personal changes, struggles, epiphanies, it's deep. It's so deep lyrically and musically… It's so hard to talk about, you really need to hear it."

Accordingly, St. Anger is nothing if not visceral — and two decades haven't sanded off those sharp edges.

As St. Anger's Recording Wound Down, Robert Trujillo Joined On Bass

While producer Bob Rock recorded the bass parts on St. Anger, his instrumental involvement 

would prove to be transitional; Robert Trujillo joined Metallica on bass in February 2001. 

Having played on all ensuing Metallica albums, 2008's Death Magnetic, 2016's Hardwired… to Self Destruct and 2023's 72 Seasons — all of which were warmly received by critics — Trujillo is now the longest-serving bassist in Metallica.

Critics Were Polarized, Then As With Now

While some contemporaneous critics knocked St. Anger as everything from "an ungodly mess" to having "underwent more processing than cat food," not everyone characterized it that way. 

Allmusic called it a "punishing, unflinching document of internal struggle"; Rolling Stone said "there's an authenticity to St. Anger's fury that none of the band's rap-metal followers can touch."

As for the band themselves, they've seemingly come to accept St. Anger, warts and all. 

"There are things I would like to change on some of the records, but it gives them so much character that you can't change them," Hetfield said in 2017. "St. Anger could use a little less tin snare drum, but those things are what make those records part of our history."

Unflinching, daring and unpolished, St. Anger is one of the ultimate "line in the sand" albums in heavy music history. Whatever your perception of this ugly-duckling entry is, take its 20-year anniversary as an opportunity to revisit its fury with fresh ears.

How Many GRAMMYs Have Metallica Won? Ahead Of New Album '72 Seasons': 6 Questions Answered

On their new album, 72 Seasons, Metallica circle the wagons and consolidate all the elements that make them… well, Metallica. Which, granted, many bands tend to do when they cross the four-decade mark. But for these eight-time GRAMMY winners, it's entirely a new look.

"There was this strange thing for many years in our band," drummer and co-founder Lars Ulrich told The New York Times in 2016. "We were in such a hurry to move forward, and in such a hurry to move away from certain perceptions about us, that we kept chasing something that we didn't really need to chase."

Much like its predecessors, 2008's Death Magnetic and 2016's Hardwired… To Self Destruct, 72 Seasons eschews any detours they've taken in the past. The songs sprawl; guitar solos are firmly back; there are no NWOBHM covers or symphonic collaborations. The title is backward-looking in a different way — a reference to the years between birth and age 18. And the ouroboros nature of 72 Seasons applies to the lyrics, too.

"Full speed or nothin'," founding vocalist and guitarist James Hetfield barks in lead single "Lux Æterna," a direct quote of "Motorbreath" from their 1983 debut album, Kill 'Em All. In "Room or Mirrors," he quotes "broken, beat and scarred" from Death Magnetic. Those 42 years together — approximately 168 seasons? — are clearly on these four men's minds.

With 72 Seasons tantalizingly close to release, take a look back, just as Metallica do on record — and find answers to six key facts about the world-dominating thrash titans.

Who Used To Be In Metallica?

While Metallica has maintained its current lineup since 2003 — Hetfield, Ulrich, guitarist Kirk Hammett and bassist Robert Trujillo — the band has some famous former members.

The spirit of their early bassist, Cliff Burton, hangs heavy in the rearview; he died in a touring van accident in 1986, right as they hit a zenith with 1986's Master of Puppets.

In a spat that honestly deserves its own article, Megadeth leader Dave Mustaine was the original lead guitarist of Metallica; he's credited as a songwriter on a handful of songs on Kill 'Em All and their celebrated second album, 1984's Ride the Lightning.

Other past members include their original bassist, Ron McGovney, and mid-period bassist, Jason Newsted, who left the band in 2001 to focus on his band Echobrain.

How Many Albums Has Metallica Sold?

Metallica have sold more than 125 million albums worldwide — 67 million of those stateside.

At press time, their best-selling album is 1991's Metallica, or The Black Album — the one with indelible hits from "Enter Sandman" to "Nothing Else Matters" — with a whopping 17 million sales.

How Many GRAMMYs Has Metallica Won?

As of 2023, Metallica have won eight GRAMMYs and been nominated for 18.

In order, those eight wins were for… 

• Best Rock Performance ("One")

• Best Metal Performance ("Stone Cold Crazy")

• Best Rock Performance (Metallica)

• Best Metal Performance ("Better Than You")

• Best Hard Rock Performance ("Whiskey in the Jar")

• Best Rock Instrumental Performance ("The Call Of Ktulu")

• Best Metal Performance ("St. Anger"),

• Best Metal Performance ("My Apocalypse")

What Is Metallica's Biggest Song?

By the standard of the Billboard Hot 100, Metallica's most successful song was "Until It Sleeps" from their 1996 album Load — their sole top 10 hit, which peaked at No. 10 and remained on the chart for 20 weeks.

(As per the Billboard 200, their most successful album is The Black Album, which peaked at No. 1, hung there for four weeks, and spent an incredible 706 weeks on the chart.)

Song-wise, though, a look at more granular Billboard categories provides a clearer picture. 

"Master of Puppets" is their biggest track in the Hot Rock & Alternative Songs chart; it peaked at No. 5. It's also their most successful song in the Rock Digital Song Sales chart, at No. 2; Hot Rock Songs chart, also at No. 2; Hard Rock Digital Song Sales chart, Hard Rock Streaming Songs, and Hot Hard Rock Songs, all at No. 1; and Rock Streaming Songs chart, at No. 3.

As per the Rock & Alternative Airplay chart, "Lux Æterna" leads the pack, with a peak position of No. 2. And while one can go much deeper into the Billboard archives for further information — and factor in non-stateside success — it's clear "Master of Puppets" comes out on top.

Does Metallica Have A New Album?

They certainly do. As stated, 72 Seasons will be released April 14 via Blackened Recordings. It was teased via four singles: "Lux Æterna," "Screaming Suicide," "If Darkness Had a Son," and the title track.

Early reviews are strong: Rolling Stone called it "some of the deepest, hardest-hitting music of their career." Opined Consequence: "It's the sound of a band having fun, laying into a ton of riffs and embracing its own legacy as metal masters."

When Is Metallica Going On Tour?

Metallica will embark on the M72 world tour starting in late April. The trek, which stretches in 2024, will bring the foursome across Europe and North America. 

Check here for their complete tour dates, and be sure to take a dive into 72 Seasons — the perfect impetus to consider the metal heroes' past, present and exceedingly bright future.
