"Peer Gynt Suite" composer (5)
I believe the answer is:
grieg
'peer gynt suite composer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for grieg that I've seen before include "Composer of the incidental music for Ibsen's Peer Gynt" , "Edvard ---, composer" , "Composer of incidental music to Peer Gynt, d.1907" , "Scandinavian composer, d. 1907" , "Norwegian composer (Peer Gynt)" .)
