OneRepublic

It sure helps to invite Timbaland to the studio. The American producer pushed all the right buttons with OneRepublic's 'Apologize' back in 2007 and their popularity has just kept growing. The Coldplayish pop-rockers from Colorado may well have one of the worst band names around – seriously, it makes them sound like they should be manufacturing and selling crap T-shirts and pre-distressed denim – but they will fill the Roundhouse with years of hits. Be prepared for the mass-singalong to 'Counting Stars'.
