Do we still care (I’m not sure I do)?

U2 will almost certainly release new music in 2013, with drummer Larry Mullen Jr. telling Irish broadcaster RTE that "something" should be out by September. According to Spin, Mullen revealed to RTE, "I'd say we will be finished by the summer -- and hopefully we will have something released by September. Hopefully what we will be able to do is release September this year and shortly afterwards, release again. That's what we want to do."

I’m pretty sure Grohl sh*ts gold…

Foo Fighters frontman Dave Grohl and Stone Sour/Slipknot vocalist Corey Taylor spoke with CBS Local about Sound City Studios, the now-closed recording facility that is the subject of Grohl's debut as a feature documentary director, Sound City:Real To Reel. Grohl was inspired to make the film after the studio closed and he bought its famous Neve analog recording board for his own home studio. Slipknot recorded its 2001 Iowa album on that board, with Taylor saying, "The thing about that Neve board is that it has such a personality. No two albums sound the same coming out of that board because of the different love that you put into it, the different variables."

Grohl, who was with Nirvana for the recording of its 1991 milestone Nevermind at Sound City, recalled, "Had we recorded that record in a different way, the music wouldn't have sounded the same. And if it didn't sound the same, it might not have had the same impact."

The event also featured the debut of the Sound City Players, an ensemble featuring a number of the musicians from the film. Grohl orchestrated a series of collaborations on new songs that appear on the movie's soundtrack. Two of those songs have already been unveiled: "Cut Me Some Slack," featuring the surviving members of Nirvana and Paul McCartney, and "From Can To Can't," which features Grohl, Taylor and Cheap Trick guitarist Rick Nielsen. The Sound City Players will perform at the Hollywood Palladium in Los Angeles on January 31st, the same night that the movie premieres at that city's Cinerama Dome and in 44 other cities around the U.S. Like the Sundance gig, the L.A. show will feature Grohl, members of Nirvana and Foo Fighters, Taylor, Nielsen, Stevie Nicks, Rick Springfield and more.
