Marie-Claire Schlameus, aka mcchaos, is a classically trained cellist, vocalist, and sound artist who reimagines the sound of the cello in the realm of experimental pop.

MC is known for euphoric warm orchestral loops and warped, glitched synth-like sounds crafted entirely from her cello using pedals and software. As a touring musician, MC reshapes the role of the cello on modern pop stages, transforming it into a cinematic, full-spectrum instrument while performing backing vocals at the same time.

MC is a founder and core member of the experimental pop string-trio toechter and experimental-noir band sometimes with others.

Live, she performs with artists like Agnes Obel and Casper. In the studio, she has collaborated with Ólafur Arnalds, Agnes Obel, Meret Becker, Swans, and Tricky. MC uses her custom setup to produce and record music for film, dance, and collaborative band projects (most recent strings for Nina Chuba, Music for Tatort, Porcelaine -Short Movie Berlinale). She currently resides in Berlin with her family.
