This Sunday, Larry visits with David Evans, a retired University of Memphis professor and music researcher, on his new book “Goin’ Up the Country: Adventured in Blues Fieldwork in the 1960s.” It recounts his trips to Mississippi and Louisiana during the mid-1960s to interview and record the last of the first generation of blues musicians. The book is a collaboration with the late folklorist Marina Bokelman, who collaborated with him on the project.
