U2 [SEP] Introduction
Within four years, they signed with Island Records and released their debut album, "Boy" (1980). Subsequent work such as their first UK number-one album, "War" (1983), and the singles "Sunday Bloody Sunday" and "Pride (In the Name of Love)" helped establish U2's reputation as a politically and socially conscious group. By the mid-1980s, they had become renowned globally for their live act, highlighted by their performance at Live Aid in 1985. The group's fifth album, "The Joshua Tree" (1987), made them international superstars and was their greatest critical and commercial success. Topping music charts around the world, it produced their only number-one singles in the US to date: "With or Without You" and "I Still Haven't Found What I'm Looking For".
