Superstar musicians will bring some festive cool, while raising money for charity, to Xfm's Winter Wonderland festival.
Performers including Kate Nash, Stereophonics and Bloc Party will headline the gigs. Acts will play alongside winners of Xfm's Rock School contest to find the three best teenage bands.
Shows in London, Glasgow, Cardiff and Manchester in December will be broadcast live and the proceeds will go to housing charity Shelter.
