Jan Boerman was a Dutch composer active in electronic music when it was still an affair of room-filling electronic machines.

Much of that music is also called ‘acousmatic’ and I suspect that this “Alchemie” (1961) composition by Boerman also falls under that label.

If you like “Alchemie”, be sure to check out Bernard Parmegiani’s masterpiece “De Natura Sonorum” (1975).
