U2 was formed in the city of Dublin, Ireland on September 25, 1976. It was founded by 14-year-old drummer Larry Mullen Jr. He posted a note on his school's notice board, asking for musicians to create a new band. There were seven teenage boys who went to their first practice. At first, the bandBand", but they later changed their name to "Feedback" and then "The Hype". The band became smaller over time, eventually becoming just four people, and they finally changed their name to "U2" once Bono, The Edge, Clayton, and Mullen were left.
