Mark Ochu is an internationally renowned lecturer and performer from Minnesota who you might have heard three years ago at UNC-Chapel Hill, when he spoke about the multicultural roots of classical music. This week, he comes to Carrboro to present "Gershwin and Black History," which juxtaposes excerpts from Dr. Martin Luther King Jr.'s speeches to Gershwin's music, to show how the composer was a role model for social change, and how his music is a metaphor for King's dream of people living together harmoniously. Gershwin's efforts to end racial prejudice will be discussed and demonstrated through performances from Porgy and Bess, Rhapsody in Blue and The Songbook. See Ochu at the Carrboro Century Center Friday, Dec. 7 at 8 p.m. Call 932-7430 for details.
