"I have worked with Heather Klein on numerous projects spanning over a decade, including Yiddish songs, art songs, operatic roles and her own original songs. Without reservation, I can say that Heather is a dream to work with. Her musical skills are varied and well-honed. She is equally at home doing 19th Century lieder, difficult modern repertoire for the operatic stage, Yiddish songs (both traditional and experimental), cantorial repertoire and pop songs. Heather’s work ethic and rehearsal technique are both excellent. She is humble and yet also confident at the same time, and in all of the years we have worked together, I have never seen the slightest prima-donna behavior in her, and others will attest to this as well. In fact, Heather’s reputation is as one of the best professionals in the scene. She is much sought after, especially because she is able to tackle the more difficult musical roles that require a trained voice. When we both worked together with the renowned San Francisco Choral Artists, Magen Solon, the conductor, marvelled that Heather was at home in both Yiddish and Opera and asked in astonishment, “Where did you find her? She’s perfect.” I recommend Heather for anything!"
