Been listening to a bunch of left-of-center postive-tip hip-hop lately, trying to find new stuff in that vein is pretty difficult.
Lesee, my playlist recently has had a lot of Solillaquists of Sound and Lyrics Born. Been partial to these two especially:
(They're both much better with good headphones or a good sub of course). If you like fast vocally intricate rap, I'd give those guys a listen.
Lateef the Truthspeaker, Gift of Gab, Living Legends and more are others I'd recommend that are pretty similar too!
