Supergroup
A supergroup is a musical group whose members are successful as solo artists or as members of other successful groups. The term became popular in the late 1960s for when members of already successful rock groups to recorded albums together, after which they normally disband. Charity supergroups, in which prominent musicians perform or record together in support of a particular cause, have been common since the 1980s. The term is most common in rock and pop music, but it has occasionally been applied to other musical genres. For example, opera superstars The Three Tenors (José Carreras, Plácido Domingo, and Luciano Pavarotti) have been called a supergroup.
