Larry Busacca/Getty Images for Clear ChannelOne of the highlights of Wednesday night's 12.12.12 -- The Concert for Sandy Relief undoubtedly was Paul McCartney's onstage collaboration with the surviving members of Nirvana. Now, new details have emerged about "Cut Me Some Slack," the rocking new song the unlikely collective of musicians performed at the star-studded benefit show at New York City's Madison Square Garden.
According to PaulMcCartney.com, a studio version of the tune was recorded earlier in 2012 at founding Nirvana drummer/Foo Fighters frontman Dave Grohl's home studio, and it will appear on the soundtrack to his upcoming documentary, Sound City. The film, which profiles Los Angeles' legendary Sound City Studios, features appearances by a wide variety of rock stars, including Neil Young, Tom Petty, John Fogerty and members of Fleetwood Mac.
Like Wednesday's performance, the track features McCartney, Grohl, Nirvana bassist Krist Novoselic and the legendary grunge group's touring guitarist, Pat Smear. The recording was overseen by Butch Vig, who produced Nirvana landmark Nevermind album.
"When I first called Paul to see if he would come and jam with us, none of us wanted to do a Beatles song or a Nirvana song, we wanted to do a new song," Grohl tells Fuse in a video interview from the 12.12.12 concert. "So we wrote and recorded a new song in a day and it's heavy as f**k." A brief audio clip of the version of "Cut Me Some Slack" that will be featured in Sound City can be heard online at CutMeSomeSlack.net.
Sound City will premiere at the 2013 Sundance Film Festival, which takes place January 17-27 at several locations in Utah. The movie then will get its official release on February 1.
