Individual performance (4)
I believe the answer is:
solo
'individual performance' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for solo that I've seen before include "Alone - card game" , "On one's own, unaccompanied" , "One-person performance" , "something for one to do" , "Alone, unaccompanied" .)
