In a new SSAA voicing, this is an outstanding arrangement of the song originally penned by Walter Robinson and a timely honor as theanti-slavery activist's image will be on the new twenty dollar bill. A cappella vocals build with a come on up followed by rhythmic vocals under the hypnotic melody. Optional cabaca part helps to imitate a train along with vocal nuances resembling the sound of chains and a train whistle. Powerful and moving!
