Filmmaker and musician Dean Mermell will present and discuss a special screening of his documentary, Twelve Pianos, about his ongoing collaborative project with fellow multi-disciplinary artist Mauro ffortissimo. Mermell and ffortissimo have brought pianos to the cliffs of the California coast, the streets of San Francisco and, for their notable Flower Piano events, the Botanical Garden in Golden Gate Park. It all began in 2013, when ffortissimo rolled an old grand piano onto the bluffs of Half Moon Bay, and continued with surprise public appearances of pianos that could be played under the open sky by both professionals and passersby. Director: Dean Mermell. (US 2017) 64 min. plus discussion. With Live Music before the show by Mariah Parker’s Indo Latin Jazz Ensemble.
