snd and mark fell are great for stuff that shifts or straight up ignores time signatures, esp. fell's latest 2 solo albums... really wanted to find track 2 of this on youtube, that boomkat preview doesn't go long enough: http://boomkat.com/downloads/365147-mark-fell-ul8
also, been forever since I've listened, but the orb's track o.o.b.e. had a really fuckin weird polyrhythm. In the live bootlegs it's more clearly in 3/4.
BT - Dynamic Symmetry. I think its 9/8 or something but i'm not that good at diagnosing these things. The section at around 7.00 is a very obvious useage. Good vid too if you can be bothered to sit it out.....
Goomba, yeah, it's got the tempo multiplier for 1x, 2x, 3/2x and 3/4x. --- American Men - Cool World Epic epic track. Beginning theme is in 4/4, but grouped into 7/4 + 9/4.
