Lemma 2 was the latest result of the Global Visual Music project of Miller Puckette, Vibeke Sorensen and Rand Steiger. The performance took place on April 8, 1999 at the Miller Theatre in New York City, and simultaneously at the Intel Conference Center in Hillboro, Oregon, as part of the 1999 Columbia University Interactive Arts Festival.
The performers were Anthony Davis and Steven Schick, in New York (with Puckette, Sorensen and Steiger on computers) and Scott Walton and Vanessa Tomlinson in Hillsboro (with Harry Castle and Shahrokh Yadegari).
The program note included the following information:
We do not aim to “teleconference” between the two performance sites. Instead, we analyze the piano and percussion sets at each location in order to make the information emerge in various ways at the other site. Vanessa’s cowbell in Oregon might sound as a similar cowbell in New York, but it might instead appear as a tomtom or as middle C on a computer-controlled piano. Moreover, computer graphics are shown at both sites which can respond in many different ways to musical gestures at either location. The heart of the piece is the exploration of new transformations made possible both by the connection between two performance spaces and by the connection between music and moving images.
