Organized by filmmakers Paula Froehle and Carolyn Faber and musician Ken Vandermark, this program combines silent shorts by Buster Keaton and D.W. Griffith with improvised music, presented not as accompaniment but as a concurrent event. The Keaton films are all superb—One Week (1920), The Playhouse (1921), and Cops (1922), about 20 minutes each. I’ve seen only the first of the Griffiths, which are each about 15 minutes—A Corner in Wheat (1909)—and that’s quite remarkable as well. The other two are The Unchanging Sea (1910) and The Female of the Species (1912). The tentative musical lineup includes Vandermark and Mats Gustafsson (reeds), Fred Lonberg-Holm (cello), Michael Zerang (drums), and Jeb Bishop (trombone).
