Join us for a moderated discussion with Alonzo King and Bernie Krause. Krause previously collaborated with Richard Blackford to compose a symphony for orchestra and wild soundscapes, which premiered in July 2014. Alonzo King’s groundbreaking choreography manipulates the laws of energy and matter that govern movement in the natural world. Together, these artists are exploring how human music and dance have evolved from the sounds and movements of other living things.

This newly added Resonance event highlights an emerging collaboration between one of ballet’s most visionary choreographers, Alonzo King, and pioneering natural soundscape artist Bernie Krause.

Take a little sound quiz with our host, Stephanie Chasteen, and learn something about how our brains locate sounds.

How do opera singers sing loud enough to be heard over an orchestra? Can an opera singer's voice really break a wine glass? What's the difference between a baritone and a soprano? Discover the answers to these questions—and more!—in this presentation for families. Join physicist and composer Dr. Brian Holmes and San Francisco Opera Center Director Sheri Greenawald to explore how the art and science of singing combine in opera.

After a week of analyzing the data from the Huygens probe, do scientists think of Titan differently? What were the unexpected findings? Which hypotheses were wrong? Which were correct? Join us as we talk to mission scientists at NASA's Jet Propulsion Laboratory and get the latest on this enigmatic moon.
