Granted there wasn't really anything from Jim in the greasy/funky/dirty direction - I understand where you're coming from. Absence of that element from Bill Evans' playing was initially a barrier for me - but only initially. I remember a musician friend trying to convince me by arguing that this wasn't essential in a jazz performance.
Well, the Paul Bryant album is somewhat greasy, without being swamped in GREEEAAAZZZE. But Jim Hall played very nice, clear guitar music, with a lovely sound, which was always a pleasure to hear, even though I never sought him out. It's not necessary to be a 'FAN' to appreciate and be glad for the existence of people who play well.
