I'm a little stuck... Click here to teach me more about this clue!

'artist livin' under hotel' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'has no new material ultimately' is the wordplay.
'no' becomes 'n' (common abbreviation).
'new' is an anagram indicator.
'material ultimately' becomes 'holbein' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'has'+'n'='hasn'
'hasn' with letters rearranged gives 'hans'.
'hans'+'holbein'='HANS HOLBEIN'
