And Sum

interactive video-music performance

George Lewis: improvised trombone and interactive music
Don Ritter: interactive video controlled by music
recorded live at New Music America Festival 1989
Experimental Intermedia Foundation, New York City

Lewis and Ritter presented approximately 20 interactive video and music works at various international venues from 1988 to 1990, including New Music America 89 (NYC), Art Institute of Chicago, The Verona Jazz Festival, FIMAV (Victoriaville, Canada), MIT Media Lab (Boston), Alternative Museum (NYC), A Space (Toronto), and The Kitchen (NYC). These performances featured electronic music and large video projections controlled by Lewis' improvisation on trombone. A radio microphone attached to the trombone transmitted audio to three computers that analyzed the notes and presented interactive music and video imagery on a large projection screen. Lewis' Voyager software produced the electronic music, while Ritter's Orpheus software provided the interactive video.
