Foo Fighters recruited rustic rocker Zac Brown for an explosive cover of Black Sabbath’s “War Pigs”. The performance kicks off the Foos’ week-long stint as musical guests for The Late Show.
The residency is in support of the band’s highly anticipated eighth studio album Sonic Highways, which features eight tracks recorded in eight different U.S. cities. HBO is also releasing a miniseries documenting the album’s intense recording process. The first episode airs October 17.
Sonic Highways is out November 10.
