Designer provides hectic art review (9)
I believe the answer is:
architect
'designer' is the definition.
(I know that designer can be written as architect)
'hectic art review' is the wordplay.
'review' is an anagram indicator.
'hectic'+'art'='hecticart'
'hecticart' is an anagram of 'ARCHITECT'.
'provides' acts as a link.
(Other definitions for architect that I've seen before include "Wren perhaps" , "professional" , "Building designer" , "Perhaps Scott" , "Author" .)
