wes montgomery- ANY and ALL of his songs. his use of octaves and his playing style will blow your mind!!!!!!
pat metheny- listen to ALL of his stuff too but try to get "bright size life", it was his (i think) first album, came out in the late 70's, and he was just a teenager. lots of great playing plus Jaco Pastorius plays bass for him on the album. originally played on electric but i play most of it on acoustic cause that's all i have...
george benson- listen to "breezin" and "affirmation" two of his songs i like best. a lot of his stuff is really jazzy and he does this skat type thing where he will sing along with whatever lines he plays on guitar. you just gotta hear it and you will see.......
"breezin" is a basic I-IV-II-V (Dmajor7, Bminor7, Eminor7, A7) jazz progression and is fun to improv and jam along with.
i have more i just cant think right now...ill get back to you later
