Family Tree: Foo Fighters

Nirvana are the most high-profile act the Foo Fighters are linked to, but that connection is only the beginning. Not surprisingly, Dave Grohl is most active during the Foos' days off, having worked with bands like Killing Joke and Queens of the Stone Age. That said, his cohorts' time with Sunny Day Real Estate and The Fire Theft shows that they don't like to sit around, either.
