Person in movement stormed in furiously (9)
I believe the answer is:
modernist
'person in movement' is the definition.
(modernism is an artistic movement)
'stormed in furiously' is the wordplay.
'furiously' is an anagram indicator.
'stormed'+'in'='stormedin'
'stormedin' is an anagram of 'MODERNIST'.
(Other definitions for modernist that I've seen before include "One shunning tradition" , "Unconventional artist" .)
