Break new ground with Bay Area artists as this episode of Spark gives you a firsthand introduction to their thoughts and processes. Meet conceptual artist Paul Kos, who was among the first artists to incorporate video, sound and interactivity into sculptural installations. Then go behind the scenes, from the initial concept to the opening night, with choreographer Joe Goode and his loyal company as they develop a brand-new performance piece -- synthesizing text, gestures and humor with high-velocity dancing. Finally, break the sound barrier at Mills College Center for Contemporary Music as we drop in on their annual open house to check out the latest from students and faculty members.
