I believe the answer is:
arts
'critic's concern' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for arts that I've seen before include "Anagram of 19" , "Poetry, music, painting etc." , "Products of human creativity" , "Aesthetic pursuits or creations" , "Wiles, skills" .)
