As a conductor of several international choirs, including the SIPA Chorale, Columbia University, it was my pleasure to invite Bill Heigen to join my Estonian Choir. Bill is an excellent singer, but he is actually much more than that. He is the consummate musician who looks at an entire score and understands it from the perspective of a composer. In addition, his work ethic is pristine. I could always count on Bill for his timeliness and excellent preparation, and only wish I could have more singers like Bill.
