My first exposure to "Whale Music" was the Rheostatics album of the same name, that I bought around 1993. I was reading the liner notes and the band said the album, which remains in a prominent place in my collection, was inspired by Canadian author Paul Quarrington's book.
I picked up the book a few months later and devoured it! An amazing read! I have since re-read the book numerous times, each time finding some new element to Desmond and his desire to complete the Whale Music.
I found the film in 1996, on video. I haven't had a lot of good experiences with Canadian film, but this one worked for me. The role of Claire could have been cast differently, but overall I think that Paul Quarrington's vision was transfered nicely from the book to the screen.
Maury Chaykin gives a moving performance as the isolated genius. The movie deals with family relationships, love, and finding someone who understands. I would strongly recommend "Whale Music" to not only music fans, but anyone who has ever lost something or someone, and tried to find their way back to the world.
