The Piano Tuner traces the life of Red Mike MacDonald, who for 50 years has tuned pianos in Cape Breton Island homes, churches and concert halls. When asked why people still have this acoustic instrument, its 88 hammers, its 230 strings, Red Mike says it’s for the love of real sound. But real sound for Red Mike is in the form of jazz. As a major figure in the Cape Breton jazz community, the stylish double-bass player introduces us to its musicians and fans, an illustrious group whose origins stretch back to a swinging Sydney of the 1930's.
