“Without a doubt he is one of the most successful choral composers anywhere. His career trajectory belies his age but none of this success has gone to his head.” (Christos Hatzis, University of Toronto News)

 “[Matthew’s] choral music is published by major publishers internationally, and it is constantly being performed.” (Toronto Star)

“His writing questions and challenges the human spirit and exemplifies why Canadian choral music is renowned around the world. His use of musical phrase is exquisite and mature; his use of harmonies decidedly unconventional yet readily understood; his marriage of text and music a testament of his beliefs about how music can support the continued existence of a creative and inspiring world. His music definitively questions the world around us and serves to respond to those questions musically and aesthetically” (Dr. Carol Beynon)
