The iTunes Festival is once again taking over Camden, presenting live performances from the world's top musical talents every night in September.

One Direction, Ellie Goulding, Lana Del Rey, Alicia Keys and Mumford & Sons are among the acts taking turns on the Roundhouse stage -- and we're giving you a chance to see it all in person.

Free tickets are available in a general lottery on the iTunes website, but we've got four pairs of tickets to every performance in the line-up. Just click here and enter your details for a chance to sing along from the front row.

Look out for Team ELLE on site at the Roundhouse, where we'll be scouting the best street style and interviewing your favourite acts. And check back for chances to win tickets to a new batch of shows soon. We wouldn't dare miss it... would you?
