I guess it depends what you want to call it... everyone sees "underground" differently. For me it looks like this...

- A Tribe Called Quest
- Arrested Development
- Atmosphere
- Classified
- Cunninlynguists
- Dangerdoom
- Hieroglyphics
- Immortal Technique
- Jedi Mind Tricks
- J5
- Murs and Slug
- P.O.S.
- People Under the Stairs
- Pharcyde
- Swollen Members
- Wisdom
