At 7 p.m. today, she will discuss her research and ideas for ending racial and economic segregation. New Carrollton Branch Library, 7414 Riverdale Rd., New Carrollton. This event is free; call 301-459-6900 for more information.

Local Folk

To call Lisa Moscatiello an accomplished folk singer is to give her short shrift. She's a songwriter, interpreter, guitarist and collaborator who has recorded songs ranging from ancient Celtic to country rock, from those of Cole Porter to Bob Dylan to her own soulful compositions. Moscatiello began singing Irish music as a teenager growing up in Arlington County, then studied history -- with a fair share of opera technique, too -- at Yale University before resuming her musical career in her hometown area in the late 1980s. The winner of more than two dozen Wammies, or Washington Area Music Association awards, Moscatiello will appear at 8 p.m. tomorrow at Joe's Movement Emporium. 3802 34th St., Mount Rainier. $12, general admission; $10, students and seniors; $6, 15 and younger. 301-699-1819.

Healthy History

During the 1930s and 1940s, Americans began to change the way they viewed fitness and their bodies. Men and women used penny scales and consulted weight charts. Professional athletes commanded the nation's attention. Fitness gurus Charles Atlas and, in the 1950s, Jack La Lanne, popularized bodybuilding and exercise. The government started regulating drugs and issuing nutrition recommendations. In Greenbelt, planners tried to make the town an oasis of healthy living. Learn about the history of fitness in Greenbelt at Greenbelt Museum's "Living the Healthy Life: Sports, Health and Fitness in the New Deal Era," opening tomorrow. The museum is at 15 Crescent Rd., Greenbelt. Admission is free. Call 301-507-6582.
