Other Projects:

Justinus Primitive

My solo musical project for the last 12 years, Justinus Primitive is vocal, experimental, and soulful. Using only my voice, I create textured loops of sounds and harmonies. I build up these layers to create experiences intended to take the listener to higher levels of consciousness.

Wave Decay Sonotorium

A sound/art installation, co-created with artist Katie Anderson. Set in the crumbling remains of a Scottish Victorian mansion, the Sonotorium is a bath of sonic sensation that uses pure tones and harmony to create an unusually peaceful ambience.
