To create Bohor (1962), Xenakis used a Lao mouth organ, called a khen, and some anklets and crotales of oriental origin. The transformation of the minimal sounds produced by these instruments and objects into a journey into the powerful darkness of sound, which alters the perception of time and transforms performance time into a single fragmented, tense, blocked moment, is the result of the Greek composer’s lucid visionariness that still arouses unconditional admiration today, more than 60 years later.
