Producer of new art genre accepts Oscar (9)
I believe the answer is:
Here is my best explanation:
'producer' is the definition.
'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.).
'artgenre' with letters rearranged gives 'generatr'.
'generatr' enclosing 'o' is 'GENERATOR'.
'of' acts as a link.
