Ben Glas (b. 1992) is an experiential composer based in Berlin. Through ephemeral compositions Glas' work questions preconceived notions between the acts of passive hearing and active listening. In seeking to discover open ended forms of music and pragmatic listening perspectives, Glas' compositions focus on the realms of subjective perception and cognition, via the use of acoustics, psychoacoustics and space as tools for sonic composition. His work has been exhibited and performed internationally, including the Portland Institute for Contemporary Art (PICA), Glasgow's Radiophrenia Festival, the Soundwave Biennial (SF) and the Czong Institute for Contemporary Art (CICA). He is currently receiving his M.A. in Sonic Studies at the UdK.

Ben Glas writes… "Anonymous Sextet for Perverted Piano is a conceptual performance piece that combines a traditional grand piano, six long-distance remote controlled vaginal/anal vibrators and the prolonged use of the piano's sustainer pedal.

The six vibrators were strategically (and preparedly) placed atop of the strings of a various grand pianos (and one harpsichord), while random strangers around the globe connected to and operated the sex toys remotely. After the random and unwitting performers had befriended and synced-up with a catfishing account linked to the six individual vibrators and controlled by three different smartphones, they then sent vibrational patterns and pulses to stimulate their assumed target. The then-kinetic vibrators bounced, slid and bopped aleatorically through the tonal possibilities that the piano and piano's soundboard itself permits. The piano's sustain pedal was held down throughout the performance, elongating the triggered notes and the good vibrations.

All tracks on side A are performed by those unwitting performers, while side B's single track was performed with (more than) a little help from my friends (Anonymous (1), Genesis Victoria, Harry Hudson-Taylor and Hayden Dean)." – Ben Glas, Berlin, 16 February 2023.
