Reading unsettling article (7)
I believe the answer is:
recital
'reading' is the definition.
(I know that reading can be written as recital)
'unsettling article' is the wordplay.
'unsettling' indicates anagramming the letters.
'article' anagrammed gives 'RECITAL'.
(Other definitions for recital that I've seen before include "Enumeration of facts" , "Chamber music concert" , "Narration" , "Telling" , "Performance of music by soloist" .)
