DuBois will perform on the church’s four-manual (keyboard) organ, containing 79 ranks of pipes, built by Austin Organs of Hartford, Connecticut, in 1952. His program will include works by Jehan Alain, Johann Sebastian Bach, César Franck, Leo Sowerby, and Charles-Marie Widor. In addition, the second half of the program will feature the monumental “Sonata: The Ninety-fourth Psalm” by 19th century German composer Julius Reubke, who was a student and disciple of Franz Liszt.
