Sergei Tcherepnin, born in 1981 in New York, recently had a solo exhibition at New York Audio Visual Arts. The exhibition featured Tcherepnin's performances, compositions, and devices that use sound and voice materials to explore physical and psychological effects on audiences. Visitors were able to interact with boxes containing mixing devices that could be manipulated to create different sounds by opening, closing, or pressing them, as well as by moving one's tongue or ears. The goal was for audiences to develop unique musical experiences based on their actions.
