The International Bluegrass Music Association brings its World of Bluegrass to Raleigh from Tuesday through Saturday. Fans may choose from a cornucopia of live acts performing on the city’s streets, as well as in clubs, restaurants, the Convention Center and Red Hat Amphitheatre. Bluegrass professionals and aspiring professionals can attend seminars, panels and workshops ranging from songwriting to using digital media to advance careers. A not-to-miss concert: North Carolina’s New Deal String Band reunites for a rare show Wednesday at the N.C. Museum of History from 5 till 7. In the late 1960s, New Deal blended ’grass with folk and rock into a style that New Grass Revival frontman Sam Bush credits as the first “newgrass” band.
