Bass studied conducting at Mannes College The New School for Music under Richard Westenburg, who was the Collegiate Chorale's director at that time.
Other notable works he presented to New York audiences with the Collegiate Chorale included Respighi's La fiamma and Puccini's Turandot with the new ending by Luciano Berio.
He also recorded and performed two of Beethoven's cantatas, Der Glorreiche Augenblick and Auf die Erhebung Leopold des Zwieten zur Kaiserwürde with sopranos Deborah Voigt and Elizabeth Futral.
Other notable singers to sing under Bass's baton included Vinson Cole, David Daniels, Lauren Flanigan, Maria Guleghina, Hei-Kyung Hong, Salvatore Licitra, and Alessandra Marc, all of them in their debuts at Carnegie Hall.
He also conducted numerous large choral works at Carnegie Hall, including Requiems by Brahms, Verdi, Mozart and Fauré, Beethoven's Missa Solemnis, Rossini's Stabat Mater, Bach's Mass in B Minor, Bernstein's Mass, Handel's Messiah and Mendelssohn's Elijah.
