Article about performance (7)
I believe the answer is:
recital
'article about performance' is the definition.
(I've seen this before)
'article about' is the wordplay.
'about' indicates an anagram.
'article' anagrammed gives 'RECITAL'.
(Other definitions for recital that I've seen before include "Concert by soloist" , "Public musical performance" , "Musician's performance" , "(Usually solo) concert" , "Performance, usually musical" .)
