Any NEW jazz blues / soul jazz artists....

Ramsey Clark's last two offering were fresh,I mean he ain't a young lion but he still roars with the best of em. Check out Red Holloway Coast to Coast with Dr. Lonnie Smith along for the ride if you want some serious flowing sax.

Jeff Golub. Anything he has done.
Unbelievable guitarist with a real ability to arrange urban jazz/blues that is not smooth jazz garbage.

I recently picked up a CD called the Crosshart Jazz Experience that I like very much; these are a couple of very talented young jazz musicians, Ryan Cross on upright bass and Lorca Hart on drums. Three exceptional pianists and two superb sax players sit in with them on various tracks.
