Sound City: Real To Reel, the soundtrack to Foo Fighters frontman Dave Grohl's documentary Sound City, is out Tuesday (March 12th) as a physical release after streaming online for the past week. The 11-track set consists of new musical collaborations featuring musicians like Paul McCartney, Trent Reznor, Corey Taylor, Rick Springfield and others. The sessions grew out of interviews that Grohl conducted for the movie, which chronicles the rise and fall of a legendary Los Angeles studio and its Neve recording board, which was used for dozens of classic albums.

One of the most powerful tunes on the soundtrack is "You Can't Fix This," with lyrics and vocals by Stevie Nicks. Grohl told us how the track came about: "She had lost her godson. Her godson had overdosed and it really broke her heart, you know. I sent her this instrumental and she basically sang this poem over the song and sent it back, and it was so moving and so real that I thought, 'Absolutely, this is gonna be great.'"

The film, which Grohl produced and directed, premiered at the Sundance Film Festival in January and is available now on DVD, VOD and in select theaters.

Grohl and an ensemble of musicians who appear in the film, dubbed the Sound City Players, have played shows in Park City, Utah during Sundance, New York City, Los Angeles and London.

The Players will next perform in Austin on Thursday (March 14th) show at the South By Southwest festival, where Dave Grohl is the keynote speaker.
