The coolest jazz i have listened to in a while has been Roy Hargrove's album "The RH Factor - Hard Groove". Roy is a superb trumpet player, who uses a lot of interesting techniques on his album, like hooking up an electric mute to a guitar amp, and adding distortion, and other such cool effects. He also has many good guests on his album doing a bit of the whole hip-hop thing, such as Q-Tip (of A Tribe Called Quest fame) and Common Sense (A terrific M.C., one of my favorites). If you are interested in the whole modern jazz mixing with hip-hop stuff at all, I would definitely recommend checking it out.
