Thanks Dad!
My dad was a big Brubeck fan in college, buying all the "Time" records as they were released. One day he put on "Unsquare Dance" (from Time Further Out)--that's the song that starts with a bass riff and finger snaps (it's in 5/4 time) before it gets really crazy with drumming on the rim and a sparse piano solo and ends with either Eugene Wright or Morello laughing at the fact that they actually made it through the song.
Anyway, I was about ten (and taking piano lessons with STRAIGHT UP stuff, Bach minuet in G, etc.) when my dad put that on, and said, "try to tap your feet to this!" I was hooked.
Hooked again in college with Jazz appreciation (common theme), and walking into MY room you'd either hear Miles/Evans Porgy and Bess or Duran Duran (did I just admit that?). Hooked again in grad school when I found a first-press copy of Blue Train in the bins...and never looked back.
