Article slammed performance (7)
I believe the answer is:
recital
'performance' is the definition.
(I know that recital is a type of performance)
'article slammed' is the wordplay.
'slammed' indicates an anagram.
'article' anagrammed gives 'RECITAL'.
(Other definitions for recital that I've seen before include "Soloist's performance" , "Concert performed by a solo musician" , "Article about musical entertainment" , "(Usually solo) concert" , "Article (anag)" .)
