From February 21 to March 2, iTunes will put on a special series of concerts at London’s AIR studios. The series is going by the name iTunes Live: London Sessions. And it comes with a catch. Tickets for the shows can’t be bought. They can only be won. To vie for the chance to catch the concerts, head to the iTunes Live website. That’s where you can also get full details on the schedule for the sessions. Artists who will performing intimate acoustic sets include Jose Gonzalez, Joe Lean and the Jing Jang Jong, Billy Bragg, Mystery Jets, Ron Sexsmith, and Roisin Murhpy. The series wraps up with the cathartic double bill of Nick Cave and the Bad Seeds and Spiritualized. All of the shows will eventually be available for download on iTunes.
