His primary instrument is the sampler which he approaches as an ‘electro-acoustic’ instrument*. In 2009 he began to work directly with loudspeakers removed from their cabinets, manipulating them and ‘preparing’ them with various textured materials, resonant objects etc. In addition to their function as the outlet for the audio signals from a sampler loaded with microscopically recorded acoustic sound, DIY audio accidents, interior field recordings etc., the loudspeakers become acoustic sound sources in their own right. Working physically with the loudspeakers, Roy provokes kinetic / acoustic interactions between the speakers and the (mostly salvaged) materials.
