Some more music from uncle (5)
I believe the answer is:
remus
'uncle' is the definition.
(I've seen this before)
'some more music from' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'REMUS' is hidden within 'more music from'.
(Other definitions for remus that I've seen before include "J. C. Harris's storyteller Uncle" , "Brother of Romulus" , "doomed wolf-suckling" , "One responsible for capital" , "Early city planner" .)
