Leading up to the premiere of Sonic Highways on HBO, the Foo Fighters kicked off their week-long residency on the Late Show with David Letterman on Monday night. In what will be an epic week in late-night TV, Dave Grohl and company were joined by country star Zac Brown for the Black Sabbath classic 'War Pigs'.

The Foo Fighters will be on Letterman all week long. The premiere of Sonic Highways, the HBO documentary with the same name as their forthcoming album, is Friday at 11pm.
