Tonight I showed Louise Ernst’s film “El Trombon de Bomba” at the Library of Congress Jazz Film Series. The 2002 documentary–a multi-layered portrait of Puerto Rican trombonist and composer William Cepeda– was shot in New York, Paris and his hometown of Loiza, PR. For the free screening, Cepeda came down from Brooklyn to introduce the film and take questions after. Let’s just say it was not your typical introduction. He spoke briefly, then played his conch shell and engaged the audience in a bit of call & response. Thanks, William!
