PREVIEW Imagine what it would be like to be working on the new span of the Bay Bridge perilously dangling in the wind, high above freezing waters, would be just another day on the job. Inspired by the female ironworkers, laborers, crane operators, and other brave souls who've helped create and tend to local bridges since the 1970s, Jo Kreiter's Flyaway Productions presents The Ballad of Polly Ann (named for the badass wife name-checked in "The Legend of John Henry's Hammer"). Like all of Kreiter's creations, Polly Ann is an "apparatus-based" performance; appropriately, the dancers will move about a bridge replica inspired by the suspension system used for the Alfred Zampa Memorial Bridge, which spans the Carquinez Strait. The Flyaway crew is used to being graceful in unlikely places (fire escapes, rooftops) and have no fear of heights (past pieces have hoisted dancers up to 100 feet over audiences) so they're the ideal company to mount this unique tribute. Polly Ann was created with help from labor historian Harvey Schwartz and musician Pamela Z, who weaves real-life bridgeworker tales into her accompanying soundscape.
