Raucous artist's son immersed in Times (6)
I believe the answer is:
brassy
'raucous' is the definition.
(thesaurus)
'artist's son immersed in times' is the wordplay.
'artist's' becomes 'ras' (Royal Academician's abbreviation).
'son' becomes 's'.
'immersed in' is an insertion indicator.
'times' becomes 'by' (I've seen this in other clues).
'ras'+'s'='rass'
'rass' inserted within 'by' is 'BRASSY'.
(Other definitions for brassy that I've seen before include "Sounding like cornet maybe" , "Cocksure" , "are showing cheek?" , "Tastelessly showy, loud" , "Tasteless and loud" .)
