U2: Irish Dublin Rock Band

In 1976, 14-year-old Larry Mullen posted a call for band members at the Temple of the Mountains Comprehensive School in Dublin. Subsequently, Paul David Hewson, David Howe Evans, Adam Clayton, and others joined. The band was originally called "Feedback Band" and officially changed its name to "U2" in 1978.

U2 performed on campus, covering songs from other bands, and their performance attracted agent Paul McGuinness. With his help, the band released their first EP "Three" and signed a four-year, four-year contract with Island Records.

In October 1980, U2's debut album "Boys" was officially released and entered the charts in both the UK and the US. In 1981, the band encountered many difficulties while producing their second album "October", but still submitted the album on time. In 1983, the third album "War" was released, which immediately caused a global sensation and topped the charts in the UK.

In 1984, U2 released their fourth album "Unforgettable Flames", under the leadership of producers Brian Ino and Daniel Ranois, which underwent a major overhaul of the band's sound and incorporated more atmospheric music techniques. In 1987, the album "Joshua Tree" was released, blending folk, blues, and rock elements to showcase U2's exploration and innovation of musical forms. This album made them an international superstar, selling over 25 million copies worldwide and winning the Album of the Year award at the 30th Grammy Awards.
