"For unfamiliar rhythms, my fave example is "Nasa Arab" -- just listen attentively to those rhythmic patterns; they're layered with an amazingly _alien_ sort of odd syncopation. Extra brain-pain points if you try and contrain it within some kind of time signature. A heavy 4/4ish drum beat does come in mid-song, but it is amidst other rhythim patterns all speaking thier own languages. Balkanized beats, if you will. That one always blows me away, in both visceral and intellectual ways..." - Thom S. Heileson
