Vocal Revolution (VR) is the men’s performing chorus of The Greater Boston Chapter of the Barbershop Harmony Society (BHS). VR is one of New England's premier a cappella performing groups and have won multiple adjudicated contests. Since chartering in 1970 as Sounds of Concord, their chorus has constantly remained dedicated to its mission of Moving Audiences and Enriching Lives Through Musical Excellence. Members come from all over the Greater Boston area and beyond. 

Most years, VR performs at Large Public Events, Senior Centers, Fundraisers, and Small Venues, and are proud that they are able to fund their work through their earnings. They have sung at Symphony Hall, the Newport Mansions, Sturbridge Village, and at the Homecoming Parade in Plymouth.
