Reznor of Nine Inch Nails (5)
I believe the answer is:
trent
'reznor of nine inch nails' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for trent that I've seen before include "Eng. river; Council of -" , "Burton's river" , "Nottingham's river" , "Chief river of the Midlands" , "Crossword frame" .)
