Jazz guitar: +2 for the great suggestions on Green and Montgomery. Among living jazz guitarists not to miss, there's Bill Frisell.

Since you want to try something new, seek out two young imaginative piano-led jazz trios: The Bad Plus from Minnesota and the Martin Wasilewski Trio from Poland.

Pat Martino and Barney Kessel are two good jazz guitarists.

For a jazz guitarist, i'd say you gotta try Lee Ritenour. Haven't heard many jazz guitarists before, but he's a really good one indeed ...
