The Ensemble Klang plays the music of Peter Adriaansz: The work of Peter Adriaansz (1966) is a musical exploration of profound existential questions, questions defiantly of the twenty-first century, about musical perception, about the nature of sound and the passage of time. Waves is music that moves very slowly; it is composed of long tones that change mostly in our perception because of incidents in the sonic ecology that surrounds them. Extremely reduced in its material, this reduction is however far from an impoverishment: listening to this music invites a quality of attention that calms the mind and creates a state of wonder. The album includes the work “Waves 5 to 7”.
