As a dancer, performer I wanted to play and control my synthesizer from within the dance.
While listening to the sonic landscapes like 'Homer Hossa' created by Boris Blank and Dieter Meier from Yello https://soundcloud.com/boris-blank-avant-garden
as well as listening to Brian Eno on Albums like 'On land' and 'Apollo' in the early eighties I had the desire to literally step in those landscapes and perform my Thai Chi based movements.
It came to my mind that it was feasible to control certain aspects of electronic synthesized sounds in real time with gestures seen through a videocamera, allowing the dancer/performer to create the music from the dance instead of dancing to music. This was back 1985.
