Performer blew up single in endless note (11)
I believe the answer is:
tragedienne
'performer' is the definition.
(tragedienne is a kind of performer)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for tragedienne that I've seen before include "Serious actress" , "Female dramatic actress" , "Performer" , "Sort of actress" .)
