Watch out for these Western Australian drum'n'bass mentalists. Last year they got one of the best crowd reactions of the event and left the In New Music We Trust Stage in pieces. This year, they bring their firepower to the main stage - you'd be a fool to miss it. Vampire Weekend have crossed the Atlantic to bring Wales a taste of their indie rock sound. Two years ago the New Yorkers were part of the INMWT lineup, this year they are headliners. Records like Cousins and Horchata from second album Contra have been all over the airwaves, and now you can hear them in person.
