"Aida" composer (5)
I believe the answer is:
verdi
'aida composer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for verdi that I've seen before include "note writer" , "Nabucco composer" , "Opera producer" , "Drive around with great opera composer" , "Giuseppe -----, 1813-1901, prolific opera composer" .)
