Apple just announced its eighth annual iTunes Festival in London, which will take place throughout the month of September. Robert Plant, Maroon 5, Pharrell Williams, Beck, Sam Smith, Blondie, Kylie, David Guetta, 5 Seconds of Summer, Calvin Harris, and Chrissie Hynde are among this year’s headliners.

Performances can be watched live or on-demand on iPhone, iPad, or iPod Touch devices, as well as with Apple TV. Local media partners are running competitions, where fans can win tickets.

Earlier this year, Apple held its first iTunes Festival in the U.S. at SXSW. Acts included Coldplay, Imagine Dragons, Pitbull, Keith Urban, and ZEDD.

The festivals are typically held in London though. The first one was in 2007 at the Institute of Contemporary Arts. The second was at KOKO in 2008.Since then, it’s been held in The Roundhouse, which is where this year’s will take place as well.

“The iTunes Festival in London is back with another stunning line-up of world class performers and tremendous new acts,” said 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.”

Since the first iTunes Festival, over 430 artists have performed for over 430,000 fans, with tens of millions of others watching performances online.

Adele, Elton John, Foo Fighters, Justin Timberlake, Kings of Leon, Lady Gaga, Katy Perry, Muse, and Paul McCartney are among other artists who have performed over the years.
