I won't try to gover the entire gamut here. Just a couple of Jazz guitarists I like. Definitely jazz guitar here, but not boring and not predictable, for sure.
1) Marvin Sewell
Quite possibly the funkiest man alive. Goes everywhere from mainstream jazz guitar to some funky blues stuff. Young guy, from Chicago. Was a key player with Casandra Wilson for a long while, before branching out. Not famous now, but he will be. Even if you can only fnd stuff wth Marvin Sewell as a sideman, as opposed to bandleader, he kicks ass.
2) Richard Bona
From Cameroun. Blends traditional jazz influences with African ones. Very nice if you can get a live album
3) Zachary Breaux
Passed away a few years ago as a very youg guy. But was already making a name as the hottest young guy in Jazz guitar. A lot of his work was as a sideman for Roy Ayers in the 1990's. He did some very good work with Ayers. Also has at least one album of his own, if not more.
