OC Parietal (moniker of Olivia van Leest) is an interdisciplinary artist based in Den Haag. She navigates sound through melodic ambient, drone noise, and minimalistic sound design. In pursuit of narrative depth, she explores themes like love, the fragility of being, and sorrow. Her framework of sound stretches from stereo recordings, to multi channel fixed media pieces, and live performances with synthesizers. OC Parietal’s music integrates electroacoustic experimentation with the refined contributions of cellists, violinists, and pianists, with whom she collaborates closely. Her debut album 'Souther' was released in May 2024 via Epiphany Records.
