Query: Prime Material Indeed :)

Prima Materia was the first Bluetech album I acquired while exploring the electronic music front beyond icons of the likes of CAN and Vangelis (1970s and onwards) :) Bluetech creates an astonishing and ingenious mix of interleaving sounds & background landscapes which catch the mind and imagination :) Prima Materia lives up to this with several outstanding tracks (like "Prophetic Sines," "Retriangulated," "White Magnesia," and "7th Phase Dub") and several really fine pieces of music with only a couple that are otherwise :) Naturally one's mood when listening plays a central role too :)
