CITY is a new glaswegian rock band formed in the summer of 2003. Founding members Steph McCrorie, Phillip Ritchie and Steve Hill set out to create something that is not unique, exclusive or incomparable - but something that is simply exciting. With influences of U2, the Cure and Jimmy Eat World, and the bands own straight-forward "no frills rock and roll" approach to writing music, a distinct and clear success has been achieved.
