Free Key Choir presents: Rust Is a Slow Fire, featuring new choral arrangements of local Bay Area artists Nüxia Peng , Lucy Broom , M'Gilvry Allen, Waterstrider, and Neder Gatmon-Segal.

The concept draws on the duality of rust and fire, two forms of oxidation that transform at different speeds. This balance—between rust’s slow change and fire’s rapid intensity—symbolizes both urgent and gradual transformation, where decay and renewal coexist.
