In the late 1960s, the term supergroup was coined to describe music groups composed of members who had already achieved fame or respect in other groups or as individual artists. The term took its name from the 1968 album Super Session with Al Kooper, Mike Bloomfield, and Stephen Stills. The coalition of Crosby, Stills and Nash (later Crosby, Stills, Nash, and Young) is another early example, given the success of their prior bands (The Byrds, Buffalo Springfield, and The Hollies respectively).
The concept of supergroup is a generalization of that of group. In other words, every group is a supergroup but not every supergroup is a group.
