With IV, Auscultation continues its explorations between minimalist ambient, drone, and meditative soundscapes. Through long immersive pieces, the Japanese project develops slow and organic music, where electronic layers, acoustic resonances, and silences occupy a central place. Oscillating between contemplation and discreet tension, the album creates a deeply cinematic and introspective atmosphere. A delicate and hypnotic work, ideal for fans of experimental ambient and contemporary atmospheric music.
