This is the 4th installment of what appears to be a cycle of documentaries exploring masterpieces by Gustav Mahler. The last one, “Everywhere and Forever” surveyed one of Mahler’s late symphonies, The Song of the Earth, and so it is interesting that the director, Jason Starr, has returned to the beginning so to speak, with Songs of a Wayfarer and the ever popular Symphony No. 1. This is an extraordinary duo of dramatic documentaries on the same DVD. The Wayfarer film featuring Thomas Hampson, as both performer and commentator, takes us through the inspiration and larger meaning of this early cycle of songs that speaks of youthful love, trauma and healing. In the longer film, “Mahler’s Titan: The Romance, Death and Triumph of a Young Musician”, we are taken to the very origins of Mahler’s symphonic music making and then proceed through the original five movement scheme of what the composer first called a Tone Poem in the Form of a Symphony. It is revelatory to learn of the programmatic impulses behind this work, an approach to imbuing music with meaning that Mahler kept developing throughout his life. The film dives deep into the emotional, philosophical and psychological journey that Mahler takes us on as he, along with his audience, confronts the challenges of living an authentic life of meaning and purpose. With gorgeous cinematography and 5.1 surround sound, the films leap off the screen.
