U2 rewrote the rock group rulebook. Over a career that now spans nearly four decades, the band have produced one hit album after another - while continually reinventing their sound - and created the template for the giant global stadium tour that all other bands now use. This is a band that measures its success in multiples of hundreds of millions. Thirteen studio albums to date have generated worldwide sales of 150 million records. No wonder Rolling Stone magazine once described them as "the biggest band in the world". And all this from a groupe whose line-up - Bono, The Edge, Adam Clayton and Larry Mullen Jr. - has remained unchanged since they formed in Dublin in 1976. From their roots in post-punk, the band have grown and incorporated all sorts of musical styles, from synth pop to gospel, but have always created socially and politically aware records that have hit a nerve with their fans. Along the way, the band performed at Live Aid in 1985, enjoyed critical acclaim for albums such as The Unforgettable Fire, The Joshua Tree and Achtung Baby!, and travelled the world several times over on the vast Zoo TV, PopMart and U2 360 tours. U2 Experience celebrates this massive act with items of removable rock memorabilia, including posters, tickets and flyers.
