Entertainer coming out of Stuttgart is temperamental (7)
I believe the answer is:
artiste
'entertainer' is the definition.
(I know that artiste is a type of music interpreter)
'out of stuttgart is temperamental' is the wordplay.
'out of' indicates the answer is hidden within the clue.
'ARTISTE' is hidden within 'stuttgart is temperamental'.
'coming' acts as a link.
(Other definitions for artiste that I've seen before include "Attires for professional entertainer" , "Attires like entertainer" , "Entertainer, singer or dancer" , "Performers" , "nightclub entertainer?" .)
