Performer in part, thespian is terrible (8)

I believe the answer is:

pianiste

'performer' is the definition.

'part thespian is terrible' is the wordplay.
'part' says the answer is hidden in the clue.
'PIANISTE' can be found hidden inside 'thespian is terrible'.

'in' acts as a link.

I've seen this clue in The Telegraph.
