WHO

a British pop group. It began as a mod group in the 1960s, and by the early 1970s was one of the most popular rock groups in the world. They were known for behaving wildly and sometimes destroying their equipment during their performances. The Who’s best-known records include My Generation (1965) and two rock operas (= stories told through a series of rock music songs), Tommy (1969) and Quadrophenia (1973).
