I've listened to a bit of DJ Shadow (don't really remember his musics), and Lyrics Born aint that bad from what I've heard. That's about it from them. I'm not really so much into underground hip hop any more, I've just been listening to a mix of Johnny Cash, Bob Dylan, Three Six Mafia, Project Pat, Lil Wyte, some ZZ Top, just kind of lax music. Haven't really been listening to too much hip hop other than Aesop Rock and El-P for now.

If anyones into techno or any of that kind of music, check out The Faint. They're a good band, not sure what to call them though. It's like techno... or trance... or electronic, or something, but with lyrics! I used to listen to them all the time. Check out their album Danse Macabre.
