I believe the answer is:

orchestra

I'm a little stuck... Click here to teach me more about this clue!

'band' is the definition.
(musical band)

I can't explain the rest of the clue.

(Other definitions for orchestra that I've seen before include "Large band playing classical music" , "Other cars (anag.)" , "Large band of players" , "Group of musical instrumentalists" , "Noted performers" .)

I've seen this clue in The Independent.
