I'm a huge fan of Jo Pass with his unique technique to play the lead, the chords and the bass line distinctly in the same solos. He used to come to the Rising Sun in Montréal once in while in the late 1970. Not to brag, but I saw him with Ella in San Francisco in 1978.
Pat Metheny also has a close link to the Montréal Jazz festival. Great improviser with a flawless technique. Unfortunately very good except with his own band, unless you like Mays.
Did anyone cite Django yet?
I did not know Prince until he died. But this solo is quite amazing:

David Gilmour for his sound and compositions
Jimmy Page of course
What do you guys think of this 16 y/o Tina S playing Dr Viossy's arrangement of Beethoven Moonlight Sonata's third movement?
