High-energy San Francisco a cappella foursome, Hookslide invites Freightgoers to join them for an evening of mind-blowing vocal beatbox percussion, booming bass and supremely tight four-part harmonies. Fearless vocal virtuosos Jon Pilat, Paul Anderson, George Hoffman, and Mayank Thanawala shrink at nothing in their feats of musical daring, cruising through voices-only covers of classics like "Mustang Sally" and "Heard It Through the Grapevine," as well as funky originals and selections from their recent album, Original Spin, with fire and finesse. They vow to "get every cell in your body and brain up and dancing" with their huge sound.
