Edvard , Norwegian composer of the incidental music for Peer Gynt by Henrik Ibsen (5)
I believe the answer is:
grieg
(Other definitions for grieg that I've seen before include "Edvard ---, composer" , "Scandinavian composer, d. 1907" , "Composer of the incidental music for Ibsen's Peer Gynt" , "Composer of incidental music to Peer Gynt, d.1907" , "Norwegian composer (Peer Gynt)" .)
