Silent street performer (4)
I believe the answer is:
mime
'silent street performer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mime that I've seen before include "Wagnerian role?" , "Silent play" , "Theatre with no speech" , "Tell a story through body movements" , "Act without words, like Marcel Marceau (4)" .)
