“What is music?” is a question that seems to be on the mind (or meme) of a lot of people lately. Last year’s best selling book This Is You Brain On Music took a scientific shot at explaining the phenomenon of rhythm, tone and timbre while indie documentary The Heart Is A Drum Machine takes a far more anecdotal approach to the question. In fact, anecdotal is what defines this film (released on DVD last week), which culls together 70-plus minutes of interview footage with an eclectic assortment of music practitioners and enthusiasts that range from Red Hot Chili Pepper guitarist John Frusciante and actress-turned-rocker Julliette Lewis to comedy team Tim and Eric and scientist Ann Druyan.
