Listening to a performance by the Voices of Liberty is one of my favorite things to do at Epcot. They are an a cappella group that performs throughout the afternoon at the American pavilion, with each performance usually taking place about 15 minutes before the American Adventure show starts. The group wears period costumes and performs American folk and patriotic songs. I am constantly in awe of their amazing voices and perfect harmonies. Every show is entertaining and always a bit different so I love going back over and over to enjoy this incredibly talented group. The Voices of Liberty is absolutely a must see while at Epcot.
