Dramatic alias (5,4)
I believe the answer is:
stage name
'alias' is the definition.
(stage name is a kind of alias)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for stage name that I've seen before include "Lady Gaga, say" , "Actor's pseudonym" , "Player could go by this" , "fresh identity" .)
