American Harmony (DVD)

American Harmony focuses on four quartets in the ultra-obsessive, zany and heartfelt world of competitive barbershop singing. Each team is trying for top honors in what turns out to be the closest and most controversial victory in the competition's 70-year history. This fascinating documentary captures all the behind-the-scenes drama of quartet life - from big egos to brain cancer - and all the glory that comes with competing simply out of love for the game.
