The line-up for the 2015 Apple Music Festival has been announced.
Pharrell Williams, Florence + The Machine and Disclosure are among the headliners at London's Roundhouse at next month's festival.
One Direction are also billed as headliners, although reports the boy band plans to split up for a year emerged after Apple announced its line up.
Apple will deliver coverage of the event on Apple's live radio station Beats 1 and the Apple Music Connect app.
"We wanted to do something really special for music fans this year," Apple's senior vice president of Internet Software and Services Eddy Cue said in a statement.
"The Apple Music Festival is a greatest hits set of ten unbelievable nights featuring some of the best performers on the planet appearing live and interacting directly with their fans on Connect and Beats 1."
The Apple Music Festival takes place over ten nights from September 19 to 28. Apple hosted the iTunes Festival in London for eight years, and now in honour of the launch of Apple Music, has renamed the event the Apple Music Festival. Apple services device users can enjoy the Apple Music Festival via Apple Music or iTunes on their iPhone, iPad, iPod touch, Mac, PC or in stunning HD with Apple TV®.
The iTunes Festival started at London's Institute of Contemporary Arts in 2007, and has seen over 550 artists perform in front of more than half a million fans and tens of millions more online and on-demand. Past performers include Adele, Beck, Coldplay, Elton John, Foo Fighters, Justin Timberlake, Kings of Leon, Lady Gaga, Katy Perry, Maroon 5, Muse, Sir Paul McCartney and many more.
Pharrell Williams said: "Wow, I'm so grateful to be performing at the Apple Music Festival. The Roundhouse is such a historic venue ... there's always a special energy in the crowd. Thank you for having me!"
Florence + The Machine said: "We're excited to be playing at this year's Apple Music Festival at the wonderful Roundhouse!"
