Apple today announced that global superstars including Justin Timberlake, Thirty Seconds to Mars, Jack Johnson and Jessie J are among the headliners at this year’s iTunes Festival in London. Running every night in September at the Roundhouse, the iTunes Festival features over 60 acts performing at the legendary venue.

The festival schedule for this year’s iTunes Festival hasn’t been posted yet, and Apple says that more details on the 30 nights of free live shows will be made available as they get closer to September. As with last year’s iTunes Festival, viewers from around the world will be able to watch live shows using iTunes, an Apple TV, or a dedicated app for iOS.

iTunes Festival used to take place in the month of July, but Apple moved it to September in 2012. Tickets will be available with a lottery system run by Apple and its media partners.
