Article about concert (7)
I believe the answer is:
recital
'concert' is the definition.
(I've seen this before)
'article about' is the wordplay.
'about' indicates anagramming the letters.
'article' anagrammed gives 'RECITAL'.
(Other definitions for recital that I've seen before include "Maybe solo musical performance" , "One's performance" , "Concert performance" , "Musical entertainment or a long account" , "(Usually solo) concert" .)
