It's hard to get into the underground scene...LoL, I'm still trying. But I think I would suggest:

Eyedea - Monster Inside (DOPE)
Aesop Rock - Daylight (Eh...I suggest this because Aesop Rock gets a lot of listen...but he's aight, this song's ok...)
Jedi Mind Tricks - I Who Have Nothing (DOPE)

If I think of more, I'll hit you back.
