Our best bet this weekend is an evening of alumni performances at Harrison School for the Arts. Roughly five dozen alumni and friends of the school will present vocal, instrumental, dance, theater and video performances in a benefit concert at 7 p.m. Saturday. (Ticket link) Genres span Broadway, Americana, classical, pop, country, indie and jazz. If you’ve followed music and arts in Lakeland, you’ll recognize performers, many of whom have returned from out of town. Check a preview video from LkldTV and see more listings after the jump.
