1930s novel clear regarding musical style (8,4)

Ross

I believe the answer is:

brighton rock

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

'1930s novel' is the definition.
(1938 novel by Graham Greene)

'clear regarding musical style' is the wordplay.
'clear regarding' becomes 'brighton' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'musical style' becomes 'rock' (rock is a music genre).
'brighton'+'rock'='BRIGHTON ROCK'

Can you help me to learn more?

(Other definitions for brighton rock that I've seen before include "Film" , "What offers colourful writing all through" , "... hard cylindrical sweet from the seaside" , "Book by Graham Greene" , "Work of fiction" .)

I've seen this clue in The Times.
