Artist offering some modern stuff (5)
I believe the answer is:
ernst
'artist' is the definition.
(max ernst)
'some modern stuff' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'ERNST' can be found hidden inside 'modern stuff'.
'offering' acts as a link.
(Other definitions for ernst that I've seen before include "artist's name" , "Max --, German painter" , "Young partner" , "He painted" , "Max -, twentieth century German Surrealist artist" .)
