Wanna feel old? The Foo Fighters have been around for so long that there's a documentary about them headed to theaters. That may seem crazy, but they have been a band for 16 years - which is exactly how long the Who existed before The Kids Are Alright came out. Judging by the trailer, Foo Fighters: Back And Forth traces the group's entire career arc – from their days as "that wacky Mentos commercial band with the Nirvana guy" through the making of their new album Wasting Light. The movie will play at 80 theaters on April 5th, and will be broadcast on VH1 three days later.
