U2 are an Irish rock band formed in Dublin in 1976. The group comprises Bono, the Edge, Adam Clayton, and Larry Mullen Jr.. Initially rooted in post-punk, U2's musical style has evolved throughout their career, yet has maintained an anthemic quality built on Bono's expressive vocals and the Edge's chiming, effects-based guitar sounds. Bono's lyrics, often embellished with spiritual imagery, focus on personal and sociopolitical themes. Popular for their live performances, the group have staged several elaborate tours over their career.
