Ei Arakawa and Sergei Tcherepnin began their audio-visual and performative collaboration in 2007. The two artists' kinetic and synesthetic performance, composition and installation works explore the materiality of sound. Ei Arakawa has initiated and participated in numerous performances and collective experiences. Most of his projects give rise to new collaborations with artists, musicians and poets. Whatever form takes of the installation, whether a festival or event, in appearing as an improvised performance, Arakawa and Tcherepnin’s work is always participative and joyfully chaotic.
