A band formed by other musicians who are already famous for their other work.

Not to be confused with the VH-1 reality show (which was, surprisingly enough, about forming a supergroup). Not to be confused with other supergroups.

Supergroups have a bad tendency not to last very long, most breaking up after five years on average. What usually happens from there is that the members return to the respective acts they were famous for in the first place. They might also be a One-Hit Wonder, collaborating for just one album or a few concerts before going back to their solo work.

Compare Dream Team (a group of similarly talented individuals are formed). See also All-Star Cast (several famous actors are all part of the same work).
