We love our quartets! Quartetting is a great opportunity for our members to reach out to the community and share our love of a cappella barbershop harmony. The quartet listed below is available for hire.


Traveling many miles of “Country Roads”, this West Virginia-based quartet has enjoyed sharing their love of music for more than a decade.
