Jon Mirsalis on Piano. The most secret pleasures in film archives are hidden far away from the feature-length titles. Here's a sampler from the George Eastman House, dedicated to all the lovers of the whimsical, the unorthodox, and the idiosyncratic. Did you know that the transition to sound cinema was promoted by a canary caught in front of a rolling camera? (A duck singing Ma, He's Making Eyes at Me in 1923 also helped in the technological revolution.) Have you ever seen a dull 1920 comedy become a psychedelic experience? The earliest known 3-D movie (we provide the anaglyph glasses), a 1918 "lost" Buster Keaton comedy with Roscoe Arbuckle in an outrageous parody of Salome, Martha Graham's dance company performing The Flute of Krishna for an early color test, and a daring Eraserhead-like short from New Zealand are the other main attractions in this guided tour across the labyrinth of a moving image collection.-Paolo Cherchi Usai
