Artist involved in track by America or Bread (7)
I believe the answer is:
paratha
'bread' is the definition.
(I've seen this before)
'artist involved in track by america' is the wordplay.
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'involved in' is an insertion indicator.
'track' becomes 'path' (synonyms).
'by' is a charade indicator (letters next to each other).
'america' becomes 'a' (common abbreviation - e.g. in organisation names).
'ra' inserted into 'path' is 'parath'.
'parath'+'a'='PARATHA'
'or' acts as a link.
(Other definitions for paratha that I've seen before include "Flat bread" , "part of Indian meal" , "Indian bread" .)
