Orbis Tertius Ensemble is an improvising group performing on a range of acoustic, analog and digital electronic instruments along with live theatrical performance. The group is conducted by the computer in an open-improvisation with interactive video programmed in Max/MSP/Jitter. The performers include, but are not limited to, Nick Lesley, Jenny Seastone Stern, David Moss, Jessica Pavone, Andres Marino, Yoni Niv, Zachary Seldess, and more. Much of the fuel for the performance comes from a short story by Jorge Luis Borges called "Tlon, Uqbar, Orbis Tertius" which is about a collaboratively invented planet, the people of which have an alternate perception of space, time, and individuality in existence.
