Semi-Toned is a British all-male a cappella group from the University of Exeter, in the United Kingdom who sing a variety of modern and classic songs. In a program called Game of Tones, Semi-Toned delivers an evening of well-known music from Broadway and the silver screen plus their own original arrangements of American and British Pop standards. It’s like “Pitch Perfect” meets “Downton Abbey.” Tickets are $25-$50 and $10 for 12 years old and under.
