Exile in Paris, The Soundtrack Paris was yesterday. So were the soulful ballads that come out of Dale Turner's sax in " "Round Midnight," Bertrand Tavernier's 1986 tribute to black expatriate jazz musicians in 1950s Paris - a melancholy slow jam of a film. Its story of a worshipful young Frenchman (François Cluzet), who watches over the alcoholic Dale, could easily be cloying, and sometimes is. But Mr. Tavernier knew what he was doing when he cast the real-life sax man Dexter Gordon as Dale. Tall and elegant, Gordon wanders through the film and Paris like a living, breathing, muttering monument, capturing something ineffable about exile in every distracted glance toward the heavens. To honor Gordon's 90th birthday (he died in 1990) the Blue Note Jazz Festival is screening " "Round Midnight" Monday at the IFC Center. A panel discussion follows with, among others, his widow, Maxine Gordon. 323 Avenue of the Americas; bluenotejazzfestival.com
