U2 is one of the most popular rock bands in the world and has been so since the 1980s. According to the RIAA, they have sold approximately 50.5 million albums in the U.S. and over 150 million worldwide, had six #1 albums in the US and nine #1 albums in UK and are widely considered one of the most successful groups of all time. The band has won 22 Grammy awards, second only to Stevie Wonder among pop artists. The band is also very politically active in human rights causes, such as the Make Poverty History campaign as well as the campaign spearheaded by Bono, DATA (Debt, AIDS, Trade in Africa).
The band was formed in Dublin on Saturday, September 25, 1976. Fourteen-year-old Larry Mullen, Jr. posted a notice on his secondary school bulletin board (Mount Temple Comprehensive School) seeking musicians for a new band. The response that followed that note resulted in seven boys attending the initial practice in Larry's kitchen. Known for about a day as "The Larry Mullen Band," the group featured Mullen on drums, Adam Clayton on bass guitar, Paul Hewson ( Bono) on vocals, Dave Evans ( The Edge) on guitar, his brother Dik Evans on guitar, and Mullen's friend Ivan McCormick on guitar. Soon after, the group settled on the name Feedback. Although known as an Irish band, two members —The Edge and Adam Clayton— are actually British by birth. McCormick was out of the core group within a few weeks, being dismissed by Adam Clayton with the excuse that he was too young to play at the bars in which U2 would be booked.
