When I was pretty young, my mom had a few jazz albums around. She preferred Kenny G, David Sanborn, John Klemmer, et al at the time, but I stole away a few others: Blossom Dearie on Verve and a Miles Best Of with material from BOTC and Blue Note. My grandparents came of age in the swing era and loved Benny Goodman and Glenn Miller, so I heard a good deal of that as a kid, too (and liked it). Later on I picked up a few things here and there that I mentioned in another thread: some Coltrane, Ornette, Mingus, Ayler, Don Cherry. At that point I felt like rock-based music was getting to be a dead-end, that I'd heard all I wanted to hear. I spent several months only listening to instrumental music before committing to jazz. That was 7 years ago and it's consumed every day since!
