Can you suggest/provide a word for a team of magnificent (intelligent or the likes) people?
I'm thinking of words that are not cliche like geniuses..
An efficient, quality team of professionals, especially specialists in their field, is often called a crack team.
crack adj. (attributive): Very good, especially at a specified activity or in a specified role. OED
Specifically in music, or by analogy to it, you might consider supergroup. From Wikipedia,
A supergroup is a music group whose members are already successful as solo artists or as part of other groups or well known in other musical professions. Usually used in the context of rock and pop music, the term has been applied to other musical genres such as The Three Tenors in opera.
