People have the wrong idea about hip-hop/rap, it's one of my favourite genres - there's more to it than just West Coast gangsta - let me give you a list - how many of these have you heard of??
Ruthless Rap Assassins
Phi Life Cypher
The Demon Boyz
Stig Of The Dump
Senser (industrial hip-hop - didn't know it was A Thing, did ya??)
Asian Dub Foundation
Goldie Lookin' Chain
So, how many of the above you heard of??
Hip-hop/rap, when done properly and done well, is urban street poetry. The best example of this is Skinnyman's only LP 'The Council Estate of Mind'. It's raw, unpolished, not like the shit Kanye, Jay Z et al come out with. I'm only really into underground stuff.
Trip-hop wise, you need to be looking at The Shamen, The KLF, Nightmares on Wax, Lionrock, Up, Bustle and Out, Baby Mammoth, Fila Brasilia, Coldcut, 9 Lazy 9, Funky Porcini, Evil Nine, etc
Hit me up if you want more suggestions.
