Conductor. Pianist. Composer.

"The performances of [Mozart] overtures and arias that Hirzer led were the work of a thoroughly cultivated musician who knows his scores, has interesting musical ideas and can convey them to an orchestra. Steady competence, leavened here and there with sparkle were the hallmarks of this very fine, much-enjoyed concert." - Calgary Herald
"Mr. Hirzer brought a combination of detailed accuracy and intense musical feeling to the work [Mr. Tambourine Man], resulting in an absolutely marvelous performance." - John Corigliano
"Special mention needs to be made of conductor Karl Hirzer, for whom this [Unsuk Chin's Graffiti] was a tremendous challenge, especially in matters of rhythm. That he could manage such a task at all was a demonstration of his skill as a conductor and ability to handle the most difficult music. This point was recognized by the players themselves, who showed their warm appreciation for his leadership." - Calgary Herald
"The Szczecin Philharmonic was conducted by Karl Hirzer, a 29-year old Canadian musician recognized by critics as a rising star in the world of conducting." - Radio Szczecin
"...the orchestra under Karl Hirzer providing a balanced, sympathetic accompaniment. Bartok’s quirky rhythms and melodies were idiomatically rendered, with much humour and nervous energy. Everything seemed to fall into place, the performance a delight from start to finish." - Calgary Herald
