Think there’s no such thing as a free gig in London? Think again, music fans. iTunes Festival is back this September for the eighth year on the trot and this year they’re giving away tickets to see Beck, Pharrell Williams with Jungle, Kasabian, Robert Plant, Sam Smith, Blondie and Chrissie Hynde and Kylie (plus many more) for zero of your hard-earned pounds. What’s the catch? It’s all done by entering a ballot – so sadly not everyone who applies will be lucky enough to be rocking out at the Roundhouse. But that shouldn’t stop you applying for as many as you like. Plus, they’ll also be adding more artists to the 30-day line-up over the coming months, so watch this space.
