Jurassic Five is awesome. I would say they're the best hip-hop group around today; I thought the Roots were, but I saw them recently and their notoriously awesome live show was only okay. Granted, it was a college show...
You could also check out Ozomatli. Spanish rock-type music, mostly, but with some rapped parts done by Jurassic Five's Charlie Tuna (he was in Ozomatli before J5 came around).
