Multimedia musician Paul D. Miller aka DJ Spooky takes us on a journey through the history of the Internet. Mixing and mashing patterns in data and music, he presents an audio-visual experience called “Quantopia” — a portrait of the Internet in sound. (This performance of “Quantopia,” a concept developed by Greg Niemeyer, is accompanied by The San Francisco Girls Chorus with visualizations from Roger Antonsen and MEDIUM LABS.)
