Starfield formed the second half of an evening of performance and conversation at the Exploratorium, San Francisco, 10th April 2014. It took the form of an introductory talk about the sounds of stars (at 42 minutes 33 seconds in the film) followed by an improvisation using a collection of these sounds (at 57 minutes 30 seconds). The first half of the perfomance, not related explicitly to cosmology, was Original Soundtracks #5. The film can be found here.
