Joseph Horowitz, who curated the first half of tonight's program and initiated design elements for part two, is the author of eight books mainly dealing with the history of classical music in the United States. Both of his last two books - Classical Music in America: A History and Artists in Exile: How Refugees from 20th Century War and Revolution Transformed the American Performing Arts - were named "best books of the year" by The Economist. As a concert producer, he was a nationally influential pioneer in thematic programming during his tenure as Executive Director of the Brooklyn Philharmonic in the 1990s. He has since 2002 served as Artistic Director of Washington's Post-Classical Ensemble, which he co-founded with Music Director Angel Gil-Ordóñez. This spring, the Ensemble presents multi-day Lou Harrison and Stravinsky festivals, hosted by George Washington University and the Music Center at Strathmore, respectively; both link with film events at the National Gallery.
