Apple today announced the artist lineup for its 2016 Apple Music Festival, the free annual concert series that takes place at the London Roundhouse theater from September to 18 to September 30.

Headliners at the festival's 10th anniversary this year will include Alicia Keys, Bastille, Britney Spears, Calvin Harris, Chance The Rapper, Elton John, Michael Bublé, OneRepublic, Robbie Williams and The 1975, Apple revealed.





"Over the past decade, the Festival has brought the biggest and best artists from all over the world to London and into the homes of millions of music fans," said Oliver Schusser, Apple's VP of International Content. "This year's Apple Music Festival builds on that incredible legacy and we couldn't be more excited to have another amazing lineup to celebrate our 10th birthday."

Prior to 2015, the event previously called the iTunes Festival lasted for a full 30 days, but was scaled down to 10 days with the revamp. Apple also now offers the music festival performances live and on-demand in the Apple Music App on iOS devices, as well as on Mac, PC, Apple TV, and Android phones.

Like last year, Apple is also set to offer special Apple Music Festival playlists, artist news, and backstage interviews via its subscription streaming music service.
