Some artists, such as Kennith Humphrey, credit their genes rather than formal art training for their talent. Humphrey, a resident of Vicksburg, Miss., links his modern, Expressionistic style of oil on canvas to the artistic talent of his half-brother, the late William Tolliver, who was known internationally for his paintings and, like Humphrey, was self-taught. This weekend, Humphrey will present some of his paintings, which depict mostly African Americans going about daily activities, at Bomani's Gallery, 7949 Annapolis Rd. in Lanham. The opening reception is from 6 to 9 p.m. Friday, and the exhibition will continue from 11 a.m. to 7 p.m. Saturday. 301-429-5858.
