U2 are an Irish rock band from Dublin formed in 1976. The group consists of Bono (lead vocals and guitar), the Edge (guitar, keyboards, and backing vocals), Adam Clayton (bass guitar), and Larry Mullen Jr. (drums and percussion). Initially rooted in post-punk, U2's sound grew to incorporate influences from many genres of popular music, yet has maintained an anthemic sound. Their lyrics, often embellished with spiritual imagery, focus on personal themes and sociopolitical concerns.

U2 have released 13 studio albums and are one of the world's best-selling music artists of all time, having sold more than 170 million records worldwide. They have won 22 Grammy Awards, more than any other band, and, in 2005, were inducted into the Rock and Roll Hall of Fame in their first year of eligibility. Rolling Stone ranked U2 at number 22 in its list of the "100 Greatest Artists of All Time". Throughout their career, as a band and as individuals, they have campaigned for human rights and philanthropic causes, including Amnesty International, Jubilee 2000, the ONE/DATA campaigns, Product Red, War Child, and Music Rising.
