Article misrepresented soloist's performance (7)
I believe the answer is:
recital
'soloist's performance' is the definition.
(I've seen this in another clue)
'article misrepresented' is the wordplay.
'misrepresented' indicates anagramming the letters.
'article' with letters rearranged gives 'RECITAL'.
(Other definitions for recital that I've seen before include "Article about musical entertainment" , "Telling" , "Public performance by a solo musician" , "Public performance of music" , "Solo music performance" .)
