I didn't know about the VoL until Fall 2008, and now I have to see them at least TWICE during every visit to Epcot. This past weekend was no different. Their talent is amazing and more people should hear them!!!
I've seen them many times before the American Adventure show. They set a great patriotic theme and have great skills. The group is very engaging with the audience. They usually draw quite a large crowd as well.
This choral group at the America pavilion can hold harmonies tighter than braids and range across the scale from baratone to first soprano. If you're nearby during a performance, be sure to stop in, take five minutes off your feet, and enjoy the songs and comical bits in between. (They also sing in colonial costumes which is extra fun.)
