Producer of new art genre accepts Oscar (9)
I believe the answer is:
generator
'producer' is the definition.
(thesaurus)
'new art genre accepts oscar' is the wordplay.
'new' indicates anagramming the letters.
'accepts' means one lot of letters goes inside another.
'oscar' becomes 'o' (phonetic alphabet: alpha, bravo, charlie etc.).
'art'+'genre'='artgenre'
'artgenre' with letters rearranged gives 'generatr'.
'generatr' enclosing 'o' is 'GENERATOR'.
'of' acts as a link.
(Other definitions for generator that I've seen before include "Existing in name only" , "It gives power" , "juice maker" , "Engine to produce electricity" , "Electricity producer" .)
