Levan’s Polkka, played on Physically Engaged Electronic Instruments (Electric Eel and Slider) by Noah Vawter with special guest player Kelly Snook. The built-in note-by-note generators allow electronic music to be played with many of the affordances of traditional instruments. Noah Vawter created these instruments as part of his work at the Computing Culture Group at MIT Media Lab. Vawter’s instruments are designed to combine some of the immediacy, portability and quirkiness of traditional instruments with the flexible timbres of electronic ones.
