Peter Vermeesch and the Flat Earth Society celebrate 20 years of “unreliable music” and the 100th anniversary of Ernst Lubitsch’s 1919 satirical silent film “The Oyster Princess” (aka “Die Austernprinzessin”), reprising their 2005 live-score production accompanying the film. “The Oyster Princess” is about greedy American oyster tycoon Mr. Quaker, a man so rich he has a butler hold his cigar while he smokes, and his spoiled daughter Ossi, who wants to marry a royal. Her father decides to buy her a prince. Mistaken identities and hijinx ensue, but the film’s main point is a scathing critique of American consumerism. Nicola Lubitsch, daughter of the esteemed director, will introduce the screening.
