Record from band is complete (4)
I believe the answer is:
disc
'record' is the definition.
(eg a CD, compact disc)
'from band is complete' is the wordplay.
'from' indicates a hidden word.
'DISC' is hidden within 'band is complete'.
(Other definitions for disc that I've seen before include "Thin flat circular object" , "something moving in the spine" , "Gramophone record" , "Flat round plate" , "Circular flat structure in the spine" .)
