Washington, D.C. native and legendary bandmaster John Philip Sousa (1854-1932) wrote a dozen operettas, six full-length operas, and over 100 marches, earning the title “March King”. He enlisted in the United States Marine Corps at an early age and went on to become the conductor of the President’s Own United States Marine Band at age 26. In 1892 he formed “Sousa and his Band”, which toured the United States and the world under his directorship for the next forty years to great acclaim. Not only was Sousa’s band hugely popular, but it also exposed audiences all over the world to the latest, cutting-edge music, bringing excerpts of Wagner’s Parsifal to New York a decade before the Metropolitan Opera staged it, and introducing ragtime to Europe, helping to spark many a composer’s interest in American music.

Sousa wrote The Pathfinder of Panama in 1915.  According to naxosdirect.com:

Pathfinder of Panama was composed for the Sousa Band’s long residency at the San Francisco Panama-Pacific Exhibition in the summer of 1915. The Sousa Band appeared alongside an all-star symphony orchestra conducted by Camille Saint-Saëns.
