Article about music performance (7)
I believe the answer is:
recital
'music performance' is the definition.
(I've seen this in another clue)
'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" , "statement of facts" , "Performance, usually musical" , "Public performance by a solo musician" , "Performance of music by soloist" .)
