Loud music and dress (5)
I believe the answer is:
frock
'dress' is the definition.
(I know that dress can be written as frock)
'loud music' is the wordplay.
'loud' becomes 'f' (short for forte - 'loud' in music).
'music' becomes 'rock' (rock is a kind of music).
'f'+'rock'='FROCK'
'and' is the link.
(Other definitions for frock that I've seen before include "something to put on" , "Party dress?" , "Demon" , "Long gown worn by priests; woman's dress" .)
