Jim was one of the true giants of the instrument, I think the first jazz musician in the modern era to really embrace the guitar for what it was, rather than trying to emulate the sax or piano. A lot of what we take for granted today as 'jazz' articulation, legato, slurs, sweeps, bends, strums, open strings ringing against fretted notes, harmonics, all got brought into the mix because of Jim. Anyone here who loves the "letting the monster out of the box and see where it walks around" approach to a tune should give an ear to "I Hear A Rhapsody" on his 1975 "Live" album. On a personal note, Jim was incredibly kind and generous to me over the years, taking time to get together for some hotel room sessions when he visited Chicago and then later introducing me to musicians on the NYC scene. Anytime I get into difficult playing circumstances, I lean on his advice to "listen to the other players and try to make musical sense".
