They were much much ahead of their time, extremely skilled musicians, if you hear noise in their music, well...
Not so keen on their reggae, though, which a find a little plodding and formulaic, but the rest is just... legendary.
When you were a kid in the late 70's, heard their Pay to Cum and ended up discovering that this blazing tune was played by 4 black guys, wow, let me tell you that you were in for a real culture shock ! Though he sported the same sort of haircut, Marley in those days was probably good enough for hippy late-comers in comparison !
(seen through the eyes of a teenager).
As someone also mentioned them, Fishbone were also much ahead of their time. I saw them live the other day and,though they no longer pack the same wallop as they used to in the 80's, they have remained an outstanding group who do teach whoever is trendy at the moment quite a few lessons. It was funny to hear their keyboard player toasting in a reggae style and including snippets of Half Pint's Greetings in one of their more recent tunes.
