Dave Grohl has just released a new trailer for his documentary, What Drives Us. The film doesn’t revolve around his bands Nirvana or the Foo Fighters. Instead, he’s created a doc about rockers and their lives on the road. The feature will utilize stories from rockers like AC/DC frontman Brian Johnson, Metallica drummer Lars Ulrich, U2 guitarist The Edge and Red Hot Chili Peppers bassist Flea to get to the heart of the live performance and why musicians thrive upon interaction with fans. What Drives Us starts streaming in just two days on April 30.
