The music for "Saint Lawrence" is a powerful tone poem charting the progress of the Calypso as it navigates the Saint Lawrence River. A ghostly waltz accompanies the team’s investigation of the wreck of "The Empress of Ireland" which, like hundreds of other ships, lies victim of the treacherous waters. A ballad tells of the frightening storms on the Great Lakes. Another part of the tone poem portrays history and habits of the Indians. The score recalls the whole epic experience.
