Erstwhile Records

Experimental music is an umbrella term for practices that prioritize exploration, process, and discovery over adherence to established genre norms. It embraces new sound sources, nonstandard tuning systems, indeterminacy and chance operations, graphic and open-form scores, extended techniques, and technology-led sound design (tape, electronics, computers, and live processing). Rather than a single style, it is a methodology and ethos: testing hypotheses about sound, structure, and performance, often blurring boundaries between composition, improvisation, sound art, and performance art. Listeners can expect unfamiliar timbres, unusual forms, and an emphasis on how music is made as much as the resulting sound.

Wandelweiser refers both to a composer collective (Edition Wandelweiser, founded in 1992) and a recognizable aesthetic that emphasizes silence, extreme quietness, long duration, and a heightened attention to sonic detail. Its music often unfolds at the threshold of audibility, inviting listeners to attend to room tone, the decay of sounds, and environmental ambience as part of the work. Scores frequently use open or flexible forms, proportional or time‑based notation, and spare materials. Rather than dramatic development, Wandelweiser pieces privilege presence, patience, and the poetics of space—where silences are treated as active, structural components rather than mere rests. While rooted in contemporary classical practice, the aesthetic intersects with experimental, electroacoustic, and ambient sensibilities, and has influenced quiet improvisation, microsound, and other reductionist currents across scenes in Europe, North America, and Japan.
