gibingus pretty much listed a lot of the same stuff I would recommend.
Bill Evans - Sunday at the Village Vanguard is another really good listen. Relaxing and laid back
As far as instrumental jazz guitar, in addition to checking out Django, Wes Montgomery, and Les Paul, make sure to try out some Charlie Christian, Joe Pass, Grant Green, Bill Frisell, and Pat Metheny as well as some Al DiMeola for a bit of fusion stuff. If you like DiMeola, be sure to check out DiMeola, DeLucia, and McLaughlin's "Friday Night in San Francisco" acoustic performance.
Fusion: Weather Report, Mahavishnu Orchestra, and Return to Forever, as well as some of Miles' later stuff are basically the definitive fusion groups (focal points from all three of the other bands had been part of Miles' various groups previously).
If any of you have never heard any Soulive, do yourselves a favor and check out their selftitled live release that came out about a year ago. You can check out some soundclips of songs (not sure if they have any from that disc) at
http://www.soulive.com/mx/site.html. They're a guitar, organ, and drum trio from Boston. Kind of a jazz-funk hybrid sound. Their live shows are a really fun time. You might hear words on a couple of the tracks, but they are almost strictly instrumental (which I definitely prefer). To give you an idea of their talent, their guitarist, Eric Krasno was among several guests to join B.B. King on stage in New York City in June of '03 for a private event held at King’s Time Square venue, which was celebrating its 3rd anniversary. Following Krasno’s solo, B.B. turned to Les Paul, who was also on stage at the time, and joked, “You better start practicing.”
