The idea of a documentary about a recording studio isn’t something to wet anyone’s appetite, but when Dave Grohl’s behind it, it kinda makes your ears pick up a bit. The nicest man in showbiz has recruited a stellar cast of his buddies for all original soundtrack, including QOTSA’s Josh Homme, Black Rebel Motorcycle Club, Trent Reznor, some of the Rage against the Machine dudes and, of course, the rest of Foo Fighters and that weird collaboration with Macca he debuted last week. Check out the trailer.
