Lately, I've been listening to alot of underground hip-hop, but the only groups I have are cyne and the 2 nujabes album. Is there anymore underground hip-hop/trip hop worth listening to?

Saul Williams

He isn't really underground and he's more rap, but T.I. is good.
Also underground rap would have to include Immortal Technique. Atmosphere, etc. those are all rap more than hip hop
