U2 formed in 1978 after Larry Mullen pinned a 'musicians wanted' ad to the notice board at Dublin's Temple Mount School. Adam Clayton had discovered rock'n'roll as a thirteen year old, buying his first acoustic guitar and then talking his parents into buying him a bass guitar. 'It just sounded good to me. Deep and fat and satisfying.
From the beginning, U2 were marked out by their passion. "A band before we could play" was how Bono put it in early interviews. Edge remembers reading UK music papers NME and Sounds every week and then hearing about this 'wild kid called Paul Hewson.
The four teenagers, who initially called themselves 'Feedback', rehearsed in Larry's Dublin kitchen, Bono on vocals, The Edge on guitar, Adam Clayton and Larry making up the rhythm section of bass and drums. Inspired by punk, but insulated from the standoffish cool by the Irish Sea, Feedback had become 'The Hype' and then 'U2' and were soon building a local reputation based on the passion of their performances.
