Returning to the UK for an eighth year — following a week of live performances in March at SXSW — the iTunes Festival will feature over 60 acts throughout September at the Roundhouse. iTunes performances can be watched live or on-demand by iOS users around the world on their iPhone, iPad or iPod touch and iTunes on their Mac or Windows computer or in HD with Apple TV. Tickets are free for competition winners only. 

"The iTunes Festival in London is back with another stunning line-up of world class performers and tremendous new acts," says Eddy Cue, Apple’s senior vice president of Internet Software and Services. "These live shows capture the heart and soul of iTunes and we love bringing them to our customers in the Roundhouse, as well as to the millions of people watching all over the world for free."

Music fans from across the world can win tickets to the iTunes Festival through competitions run by local media partners. In the UK, fans can win tickets by entering ballots on iTunes, as well as through select media partners including Global Radio and the London Evening Standard. 

Since the inaugural Festival at London’s Institute for Contemporary Arts in 2007, over 430 artists have performed in front of more than 430,000 fans and tens of millions more online and on-demand. Now in its eighth year, the iTunes Festival has played host to performers including Adele, Coldplay, Elton John, Foo Fighters, Justin Timberlake, Kings of Leon, Lady Gaga, Katy Perry, Muse, Sir Paul McCartney and many, many more.
