Groovy jammy jazzy stuff, eh?
Have you gotten into any of the musicians that appear on those SM discs? Guys like Skerik, Charlie Hunter, and Karl Denson? Skerik has some pretty far out stuff, cave-man jazz I like to call it (the Critters Buggin stuff particularly). Charlie Hunter is typically awesome. If you don't have the original Garage a Trois disk Mysteryfunk, it's a keeper. Denson, or any of the Greyboy Allstar members, can really lay down irresistable dance grooves.
Matin Medeski and Wood? 'End of the World Party' is pretty awesome place to start.
Also, more in the neo-hippy vein, Garaj Mahal out of Chicago can get their groove on. Their studio album is a little phishy smelling at times, but still good. Less jazzy, but pretty good rockin jam band that can get their groove on.
Old timey groovy soul jazz? Everyone should have Blue Note Rare Grooves, the sampler album with John Patten, Stanley Turrentine, Jack McDuff, Jimmy McGriff, et al. From beginning to end, that one will have you in a soul drenched trance.
I would also recommend checking out some of the shows on
www.KUVO.org, particularly the ones on after 10pm. (KUVO is the Denver jazz radio station, a great station.)
