Powerful early work from Iannis Xenakis – and possibly the greatest demonstration of the concept of electro-acoustic you could hope to find! The mixture of sounds, shapes, and textures here is pure Xenakis – definitely at a level that's similar to some of his contemporaries on the European electronic scene of the time – but with a raw power, and almost organic sense of disturbance that's gone onto have a huge influence on years of musicians in many different scenes. Titles include "Orient Occident", "Bohar", "Concret PH", and "Diamorphoses". LP, Vinyl record album
