I was really enjoying this discussion - then up popped Tchai- bleedin'-kovsky, trying to turn a primitive music (?) form into a subject for academic study. The practitioners of this stuff wouldn't recognise a polyrythym if it bit them on the bum. It's just a device that allows people with little talent to jump onto a stage, make curious gestures with their fingers and launch into a diatribe that satisfies their need to be a victim ( there's a lot of this about these days - it sort of provides an excuse for not trying to improve yourself ). Feminist musicologist indeeed !
