iTunes Festival 2014 Adds Paolo Nutini, Lenny Kravitz, Elbow

Apple's 2014 London iTunes Festival lineup just filled out a little more with Paolo Nutini, Lenny Kravitz, and Elbow all getting show dates. The annual music event includes 30 days of free concerts from big name artists at London's Roundhouse, but tickets are available only through a lottery system.

Apple previously announced that Maroon 5, Beck, Pharrell Williams, Sam Smith, Blondie, Kylie, David Guetta, 5 Seconds of Summer, Calvin Harris, and Chrissie Hynde will be performing, and several other artists are on board, too.

The concerts will be streamed via Apple TV, so music fans that don't win show tickets can still see the performances. Show dates and times are available on Apple's iTunes Festival website.
