Celeste Chan. For Celeste Chan -- a writer, filmmaker, teacher, artist and activist -- the medium is whatever fits the message. Raised by a pair of Berkeley-educated “halfway hippies” and home-schooled, Chan found her footing in a post-Riot Grrl Olympia, Washington, then shifted into high gear when she arrived in San Francisco in 2004. This week, the founder of Queer Rebels and teaching artist for the Queer Ancestors Project brings her story (and some pretty cool eyeglasses) to the GrottoPod to offer her thoughts on shining light on under-recognized artists and their work. “It’s about amplifying marginalized and unheard voices, carving out space, and carving out space for my own voice within that.”
