The class was called “Music in U.S. Prisons,” a college-level course taught by Ben Harbert, a lanky, blue-eyed associate professor in Georgetown’s music department. Harbert put the course together for the inaugural semester of the university’s Prison Scholars Program, which offers a variety of classes to inmates in the D.C. Jail. Several of the course offerings, including Harbert’s, were “inside-out” courses made up of both inmates and Georgetown undergraduates.
