I too got turned on to jazz at a high end audio shop ("Keith Jarrett at the Blue Note"). But I really got HOOKED when I befriended another customer I met while in that same shop. He invited me over and introduced me to his extensive classic jazz collection. It's hard to know which one really got me; it would probably be between "Kind of Blue" and Keith Jarrett's "Koln Concert".
Who was your first
What was the first jazz artist that got you hooked on jazz? I was in a high end audio store and the salesperson put on Dianna Krall All or nothing at all on a pair of B&W's and ever since then I was hooked. And that is what led me down this never ending audio addiction.
