That other obsession is percussion. From the way I put it together, she'd always loved percussion-heavy music, stuff with lots of polyrhythms. Her tastes became even more arcane and twisted after her Echo Mirage days, until no commercially available music would suit her. That was when she built herself a computerized drum machine, programming it to write and play its own intersecting polyrhythms, using insanely complex weighting algorithms to make it stay with the stuff she finds pleasing. And that's the crux of the matter. To anyone else, Buddy's "music" sounds like street repairs or like driving around with rocks in your hubcaps. To make it worse, she plays it so loud I'm surprised Sea-Tac Airport hasn't threatened to move.
