Eight fresh young stars arrive at the music mansion to compete for an amazing prize - the chance to perform at Radio 1's Big Weekend. But they aren't the only new faces arriving in the mansion. On her own personal journey is new presenter Anna Maynard, and working with the singers is a new musical director, Max Cooke.

But the big question is who will walk away with the win in the very first sing-off.
