As a full-time college professor from early in my career on, I enjoyed performing as actively as job and family circumstance allowed, primarily in the mid-west, until 1996.  From ca. 1990 until 1996 I began to experience symptoms of weakening, leading to a diagnosis of aesthenic vocal folds from early onset presbylarynx (aging) that resulted in vocal fold bowing.  This was determined to be constitutional (genetic) in origin.  My “swan song” as far as public performance was as the Evangelist in Bach’s St John Passion at Lawrence University in April of 1996.  Since that time I have enjoyed making music as a collaborative pianist with faculty colleagues and with my voice students.

The recordings below are mostly non-professional videos of my singing in the years 1988 to 1992.  While the video quality is poor, the audio quality is a fair representation of my singing.
