Horatio Oratorio is an exploration through the history of recorded sound. The earliest recording and playback technologies and rare mechanical-acoustic string instruments are combined with vintage and state-of-the-art electronics. A magnificent array of acoustic horns and custom-built loudspeakers project sound from historic wax cylinder phonographs, gramophones and stroh violins, layered and transformed by live digital sound processing.

He lives and works in London, England.
