Dave Grohl directs this tribute to the infamous L.A. recording studio that gave birth to Nirvana’s Nevermind, Fleetwood Mac’s Rumours, Tom Petty’s Damn the Torpedoes … and the list goes on. Much of the movie deals with the studio’s history leading up to its recent shutdown. Grohl actually purchased the legendary soundboard and put it in his own studio, where he recorded a forthcoming album featuring Paul McCartney, the surviving Nirvana bandmates, Stevie Nicks, Rick Springfield and more. The film features footage of that album’s recording, most notably with McCartney, who puts forth a scorching “Helter Skelter”-like number with Grohl and the remaining Nirvana members. This is a great, solid piece of rock history filmmaking. Grohl’s love for the subject permeates the entire undertaking.
