The trio will be among the main acts at the music extravaganza, formerly known as the iTunes Festival, which is set to take place from September 18th to September 30th.

On returning to the UK, 'Make Me' hitmaker Britney said: "I'm so excited to go back to London, which is a special place for me to visit and I'm really looking forward to performing at the Apple Music Festival. It's also their 10th birthday! It's going to be a great party."

'Tiny Dancer' hitmaker Elton, 69, said:"I am so excited to be playing at the Roundhouse. I love London and can't wait to share this fantastic experience at the Apple Music Festival with my fans."

And bringing her "magic", Alicia added: "I love London and performing at the Roundhouse! I can't wait to see you there. It's going to be magic!!"

And 'Good Grief' hitmakers Bastille can't wait to perform their first hometown show since releasing their latest LP 'Wild World'.

The indie rockers - fronted by Dan Smith - said: "We're massively excited to play Apple Music Festival for many reasons, but mainly because it'll be our first proper London show after the release of our new album, 'Wild World.'

"The Roundhouse is such a beautiful venue and it's in our hometown, so I can't think of a better place to play a bunch of new songs for the first time."

And OneRepublic said: "We are looking forward to returning to the iconic Roundhouse this year to play one of our favourite festivals, the Apple Music Festival, and perform new music for our fans!"
