Precursor to reggae (3)
I believe the answer is:
ska
'precursor to reggae' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ska that I've seen before include "Dancehall music" , "Jamaican music, forerunner of reggae" , "popular music" , "Noted genre" , "Jamaican music style" .)
