The Four Seasons composer (7)
I believe the answer is:
vivaldi
'the four seasons composer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for vivaldi that I've seen before include "Venetian composer ("The Red Priest"), d. 1741" , "Italian composer (the Red Priest) , d.1741" , "Italian composer of 'The Four Seasons'" , "Italian composer known as "the red priest"" , "Italian composer, Antonio (d. 1741)" .)
