>> History of U2, Formation and early years (1976–1980)

The band formed in Dublin on 25 September 1976. Larry Mullen, Jr., then a 14-year-old student at Mount Temple Comprehensive School, posted a note on the school's notice board in search of musicians for a new band—six people responded. Setting up in his kitchen, Mullen was on drums, with Paul Hewson (Bono) on lead vocals; David Evans (The Edge) and his older brother Dik Evans on guitar; Adam Clayton, a friend of the Evans brothers on bass guitar; and initially Ivan McCormick and Peter Martin, two other friends of Mullen Mullen later described it as "'The Larry Mullen Band' for about ten minutes, then Bono walked in and blew any chance I had of being in charge." Soon after, the group settled on the name "Feedback" because it was one of the few technical terms they knew. Martin did not return after the first practice, and McCormick left the group within a few weeks. Most of the group's initial material consisted of cover songs, which the band admitted was not their forte. Some of the earliest influences on the band were emerging punk rock acts, such as The Jam, The Clash, Buzzcocks, and Sex Pistols. The popularity of punk rock convinced the group that musical proficiency was not a prerequisite to being successful.

In March 1977, the band changed their name to The Hype. Dik Evans, who was older and by this time at college, was becoming the odd man out. The rest of the band was leaning towards the idea of a four-piece ensemble and he was "phased out" in March 1978. During a farewell concert in the Presbyterian Church Hall in Howth, which featured The Hype playing covers, Dik ceremonially walked offstage. The remaining four band members completed the concert playing original material as "U2". Steve Averill, a punk rock musician (with The Radiators) and family friend of Clayton's, had suggested six potential names from which the band chose "U2" for its ambiguity and open-ended interpretations, and because it was the name that they disliked the least.

On Saint Patrick's Day in 1978, U2 won a talent show in Limerick. The prize consisted of £500 and studio time to record a demo which would be heard by CBS Ireland, a record label. This win was an important milestone and affirmation for the fledgling band. U2 recorded their first demo tape at Keystone Studios in Dublin in May 1978. Hot Press magazine was influential in shaping the band's future; in May, Paul McGuinness, who had earlier been introduced to the band by the publication's journalist Bill Graham, agreed to be U2's manager The group's first release, an Ireland-only EP entitled Three, was released in September 1979 and was their first Irish chart success.In December 1979, U2 performed in London for their first shows outside Ireland, although they were unable to gain much attention from audiences or critics. In February 1980, their second single "Another Day" was released on the CBS label, but again only for the Irish market.
