Componium Ensemble has been played on NTS shows including RVNG Intl. Presents Friends & Fiends, with Efflorescence (For 3 Bowed Harpsichords, 2 Bass Clarinets, Flute And Cello) first played on 10 December 2025.

An “indeterminate chamber music” ensemble helmed by Spencer Doran of Visible Cloaks. Situated in a lineage of automated music that traces back to the ancient Greeks. The history of automated instruments reaches back as far as Archimedes and his "organum hydraulicum”, but it was the Banū Mūsā brothers in 9th-century Baghdad who first perfected the concept of a programmable, automated musician: a mechanically controlled flute which performed using a cistern’s hydraulic water pressure and a system of arrangeable punchcards using a visionary proto-MIDI structure. Componium Ensemble features a wide and intriguing range of digitally modeled versions of celesta, prepared piano, bowed harpsichord, flute, tingklik, and more — sequenced through algorithmic processes rather than played live. The music feels performed, but it’s the result of automated composition and digital orchestration.
