Article about a performance (7)
I believe the answer is:
recital
'a performance' is the definition.
(recital is a kind of performance)
'article about' is the wordplay.
'about' indicates an anagram.
'article' anagrammed gives 'RECITAL'.
(Other definitions for recital that I've seen before include "Concert performance" , "Telling" , "Performance of music by soloist" , "statement of facts" , "Concert performed by a solo musician" .)
