Wrong rock concert I reviewed initially (9)
I believe the answer is:
incorrect
'wrong' is the definition.
(I know that wrong can be written as incorrect)
'rock concert i reviewed initially' is the wordplay.
'rock' is an anagram indicator (the solver must 'rock' the letters around).
'initially' indicates taking the first letters.
The initial letter of 'reviewed' is 'r'.
'concert'+'i'+'r'='concertir'
'concertir' with letters rearranged gives 'INCORRECT'.
(Other definitions for incorrect that I've seen before include "Not accurate" , "False, wrong" , "Erroneous" , "Place of refuge" .)
