One of Scott Joplin’s masterpieces, and one of the finest performances on William Appling’s recording, is not even a rag but a habañera (or contradanza) called “Solace.” Joplin actually subtitled the piece “A Mexican Serenade,” but whatever form or style you wish to call it, “Solace” is a soulful gem. In this interpretation, William Appling’s deep love for and profound understanding of Scott Joplin’s music is never more evident.
