Indian city for crazy artists (6)
I believe the answer is:
madras
'indian city' is the definition.
(I've seen this before)
'crazy artists' is the wordplay.
'crazy' becomes 'mad' (synonyms).
'artists' becomes 'RA's' (Royal Academicians abbreviation).
'mad'+'ras'='MADRAS'
'for' is the link.
(Other definitions for madras that I've seen before include "something hot?" , "Former name of Indian city and state" , "Indian city now known as Chennai, and medium hot curry" , "Variety of curry" , "Tamil Nadu capital; a hottish curry" .)
