Solo electric cello and at least 9 Carousel slide projector (Kodak Carousel) filled with a minimum of 80 hand made slides in each one.
The visuals covered the entire periphery of the audience’s vision including the ceilings and floors.
If I recall correctly, the music was in 5.1 surround with my feet controlling which speakers sounds went to.
It was a complete immersion!
