Why You Do This(2010)

Why You Do This is a documentary following Michael Dafferner, a satellite engineer and vocalist for math-core band Car Bomb, as he grapples with the tension between his day job and musical ambitions. Over three years and multiple tours, Dafferner interviews fellow musicians in the metal scene—including members of Lamb of God and Gojira—to understand why they pursue such an uncompromising, commercially risky genre. The film explores the personal sacrifices and hidden rewards of choosing an unpopular musical path, examining what success truly means for bands operating outside the mainstream. Through candid conversations with artists navigating the same struggle between financial stability and artistic passion, Why You Do This reveals the deeper motivations driving musicians to take extraordinary risks for their craft.
