Leo Küpper

condition (record/cover): NM / NM | The album showcases Leo Küpper’s pioneering work in electroacoustic music and his fascination with the intersection of human voice and machine-generated sound. L’Enclume Des Forces (1967–1971): A 13-minute piece featuring the voices of Exequiel Virasoro and Jean-Claude Frison. It explores the "anvil of forces" through dense, textured sonic layers. Électro-poème (1963–1964): An early work for a mixed choir of twelve children, where vocal "logatomes" (meaningless syllables) are electronically manipulated to create a rhythmic, synthetic language. Automatismes Sonores (1961–1971): A 26-minute exploration of purely electronic structures, often divided into five parts. This work was developed using Küpper's self-built GAME (Générateur Automatique de Musique Electronique), a machine designed to generate complex interactions between sound and space.
