Django should be left out for reasons similar to Christian; he would dominate the list. As it is, with all the Blue Note fans on this board, Green has a bit of an unfair advantage. For me it was a three-way tie between Farlow, Burrell, and Jim Hall (I figured Montgomery is such a towering figure that he would also clean up---looks like I may have been wrong on that). So I voted for Jim Hall, always swinging, tasteful, & elegant in a broad variety of contexts.
