This high-energy San Francisco a cappella foursome invites Freightgoers to join them in celebrating their 100th show, complete with mind-blowing vocal beatbox percussion, booming bass and supremely tight four-part harmonies, not to mention a cake, some special guests, and their recently released debut album, Original Spin. Fearless vocal virtuosos Jon Pilat, Paul Anderson, George Hoffman, and Mayank Thanawala shrink at nothing in their choice of material, cruising through voices-only covers of classics like "Mustang Sally" and "Heard It Through the Grapevine," as well as funky originals, with fire and finesse. They vow to "get every cell in your body and brain up and dancing" with their huge sound.
