WEDNESDAY

In 1938, 23-year-old folklorist Alan Lomax sat down in the Library of Congress’ Coolidge Auditorium with a portable disc recorder and a 48-year-old Jelly Roll Morton, who was sitting at a piano. Morton, a onetime pimp, told him stories about his days creating jazz in New Orleans brothels and played some tunes. In three years, Morton would be dead, but Lomax spent the rest of the 20th century recording Muddy Waters, Woody Guthrie, and countless other musicians known and unknown throughout the world. To open the two-day symposium “The Lomax Legacy: Folklore in a Globalizing Century,” jazz scholar John Szwed, who’s writing a book on Morton, and avant-jazz pianist Dave Burrell will offer a program titled “Mister Jelly Roll, Mister Lomax, and the Invention of Jazz” at noon at the Library of Congress’ Coolidge Auditorium, Jefferson Building, 10 1st St. SE. Free. (202) 707-5677. (Steve Kiviat)
