Brits from West Sussex, drummer Ben Thatcher (left) and Mike Kerr formed Royal Blood in 2013, gained support from the Arctic Monkeys, and released their self-titled debut album the following year to acclaim. Speaking with Chicago Chapter at Lollapalooza 2017, their follow-up album had been released in the beginning of the summer. "It was incredibly hard to write the title track from How Did We Get So Dark?," Kerr said, explaining how their songwriting process took on aspects of quilting, for the first time, as pieces wound up in an unexpected order. "It's nice playing festivals because you get to play outside and you get to see other bands and hang out with other bands," Kerr also said. "It's a good vibe." Recreating the studio layers on the road is a challenge, though, as Thatcher triggers samples live. The two performers agree, "Sometimes it goes very wrong."
