Indie pop band Bastille are more than a little excited about the chance to play in London, explaining: "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."

The Apple Music Festival runs from 18 September to 30 September (16).
