Electro-chamber music: around Mantra

Image
The fourth session of my Electro-chamber music course was dedicated to Karlheinz Stockhausen's classic Mantra.This composition for two pianos (with rind modulators, crotales, woodblock, and more) is a beautiful example of new soundscapes unveiled with live electronic music.
