The Natural History of the Water Closet is a self-proclaimed documentary cantata, a film in which the soundtrack carries as much weight as the subject. Composer Paul Alan Levi creates a vibrant, operatic score to highlight the distinctive topic of interest. Produced and directed by Samuel Hudson for PBS, the short documentary offers a history and explanation of the modern water closet. The film includes appealing animation, demonstrations, and interviews with distinguished architects. Hudson packages everything you ever wanted to learn about the water closet into an entertaining half hour of music, dancing toilets, and expert insight.
