Known for her work across jazz, theatre, and classical music contexts, Berlinde Deman is a tuba player and sound sculptor who is a part of the Flat Earth Society Orchestra. Cinematic and sombre, Deman's output is moving and unique, thanks in part to the incredible timbres of her instrument of choice: she uses a sixteenth-century instrument called the serpent, a distant, mysterious predecessor of the tuba which was developed in the Renaissance era. Through the use of layering and looping, she constructs an ever-expanding sound of subtle melodic growth and swarming harmonic dissonance. Her debut album Plank 9 (2025) is a work of pure creativity and exploration, combining minimal insectoid murmurs with elysian ambient horn-song. Somehow, the tones this ancient instrument create have an ethereal, teleportational effect, dragging listeners into a different world of perception: one of wandering alone in nature, of feeling the creaks in one's bones, or of sensing the unsettling calm before a storm.
