Lead singer Dolores O'Riordan of the Cranberries died suddenly on Jan. 15 in London while in town for a recording session, according to a posting by her band on Facebook. While The Irish Times reports the Cranberries cancelled several 2017 tour dates due to O'Riordan's "medical reasons associated with a back problem," no cause of death has been officially disclosed. She was 46 years old.

A gifted songwriter and vocalist whose ballads helped define alt-pop in the '90s, in 1989 O'Riordan auditioned to join the iconic Irish band formed by brothers Noel and Mike Hogan. They released their debut album, Everybody Else Is Doing It, So Why Can't We?, in 1993, including the sleeper hits "Dreams" and "Linger," both of which charted on the Billboard Hot 100.

The band followed up with the successful 1994 album, No Need To Argue, which included the hit single "Zombie." Thanks to their early success, Rolling Stone called the band "Ireland's biggest musical export since U2."

The Cranberries released a handful of additional albums through 2001 before taking a hiatus. The band reunited in 2009 and released their first album in more than a decade with 2012's Roses. Their most recent release was 2017's Something Else.

Reactions to O'Riordan's loss have poured onto social media, with celebrities such as  GRAMMY host James Corden, Michelle Branch, Vanessa Carlton, and Hozier recognizing her extraordinary talent and influence.
