In the early days of Foo Fighters, Dave Grohl used to have a pre-show tradition that's not what you might expect.
During the band's appearance on The Late Late Show with James Corden, guitarist Chris Shifflett said Grohl used to blast a particular song on a boom box before every concert.
The song? Juvenile's "Back That Azz Up" - which was brand new at the time. Shiflett called it "our pre-show warm-up".
