Since 2007, Apple's hosted an annual iTunes Festival in London, and 2013 will be no exception: The company on Thursday announced that Justin Timberlake, Thirty Seconds to Mars, Jack Johnson, Jessie J, and nearly 60 other bands will headline this year's incarnation of the festival.
The concert series runs every night in September at The Roundhouse, and even if you can't attend in person, you can still watch. Apple streams the iTunes Festival both live and on-demand, and it can be watched from iOS devices, Macs, PCs, and the Apple TV--in high definition, if your devices support it.
Apple says "local media partners" around the world will give away tickets to the event through various promotions and competitions. So if you live in the U.S., Australia, Brazil, Canada, Europe, Japan, or Mexico, watch for iTunes Festival ticket giveaways. In the United Kingdom, fans can win tickets using the iTunes Festival app, via iTunes, or from media partners including Channel 4, Global Radio, and Metro.
Sir Paul McCartney and Amy Winehouse performed at the first edition of the iTunes Festival, and more than 370 artists have played the concert since then.
