“Nothing makes me feel more like a human being on planet Earth than listening to My Bloody Valentine or [f—ing] Al Green or the Beatles or Slayer,” Dave Grohl, the founder and frontman of the Foo Fighters, told The Washington Post in 2015. Grohl came up as Nirvana’s drummer, yet despite his gritty background he is now known for his earnestness, and a style that might be characterized as Dad-rock. Made up of middle-aged musicians who cut their teeth on grunge, the Foo Fighters have ranged from alt-rock to radio-friendly rock hits. But as the band has aged, it’s become increasingly willing to step outside strict definitions of “rock n’ roll”—there was, for instance, a controversial collaboration with Diddy. For its latest album, the band partnered with Greg Kurstin, producer and songwriter for the likes of Adele and Kelly Clarkson. This marks the group’s biggest swerve into the realm of pop. —C.J.F.
