For the past few years the Hyde Park Jazz Festival has featured a sidebar of free film screenings. The tradition continues this Saturday with three half-hour documentaries from the late 1960s by British filmmaker and scholar Dick Fontaine. The films, all of them screening from 16-millimeter, will play at Black Cinema House, which is copresenting the program along with Michael J. Phillips of South Side Projections. Screening at 2 PM is Who’s Crazy? (1966), which documents a collaboration between Ornette Coleman and the Living Theatre, America’s longest-running experimental theater company, for a stage production in Paris. Who Is Sonny Rollins? (1968) plays at 2:45 PM, and Sound??? (1967) rounds out the program at 3:30 PM. (Among his other achievements, Fontaine employed multiple question marks in his titles decades before the Flaming Lips even formed. His personal website is pretty rad too.) The latter film features avant-garde saxophonist Rahsaan Roland Kirk and composer John Cage. It’s also available on YouTube (as you can see above), so you can still check it out if you can’t make it to Hyde Park on Saturday.
