In 1974, nine musicians came together in Appleton, Wisconsin, to form Matrix, a jazz fusion ensemble. Led by composer and keyboardist John Harmon, the group rose to prominence on the festival circuit before recording six acclaimed albums. Follow Harmon as he tells the story of the band, from their beginnings on the road in the Midwest to their greatest successes to their reunion tours that brought them back together. From the Heart brings you into the inner workings of a highly influential music group, as well as closer to the man who made it all happen.
