Third album, following 2006's 'Under The Iron Sea', from the hugely successful Brit pop-rock stars whose piano-led, emotive and melancholy songs have placed them in the same bracket as fellow travellers Coldplay and Snow Patrol. On 'Perfect Symmetry' they take some chances with their sound, experimenting with synthesizers and more aggressive beats such as those to be heard on the 80s-influenced, free download single'Spiralling'.
