Solo for Renee Fleming (4)
I believe the answer is:
aria
'solo for renee fleming' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aria that I've seen before include "Song from an opera (4)" , "Summertime perhaps" , "selection of opera" , "Nessun Dorma, for example" , "Operatic part" .)
