Sillyconductor is the artistic moniker of Cătălin Matei, a Romanian sound artist based in Bucharest. He is recognized for his work as a sound designer, composer, performer and educator, with a diverse portfolio that includes music for silent films, games, animations, fashion shows, theatre and dance performances. His works often feature self-built or modified instruments, field recordings, and improvisational techniques that push the boundaries of traditional music-making. His primary focus is sound and its relationship with science or mathematics, creating instruments or installations that simultaneously explore sound, technology, and the environment. In recent years, his attention has shifted to bio linguistic installations and the sonification of inaudible phenomena, from archaeological sites to jars of algae.
