Go over new art and poetry (8)
I believe the answer is:
traverse
'go over' is the definition.
(thesaurus)
'new art and poetry' is the wordplay.
'new' is an anagram indicator.
'and' means one lot of letters go next to another.
'poetry' becomes 'verse' (synonyms).
'art' with letters rearranged gives 'tra'.
'tra'+'verse'='TRAVERSE'
(Other definitions for traverse that I've seen before include "cover" , "Travel across or pass over" , "Move across" , "In mountaineering, a steep slope to be crossed from side to side" , "Cross sideways" .)
