Tony Iommi's Damaged Fingers Built the Foundation of Heavy Metal
Tony Iommi's 1965 factory accident, which cost him the tips of two fretting fingers, directly produced the downtuned, chord-heavy riff vocabulary that defines hard rock and heavy metal. Inspired by Django Reinhardt and driven by physical necessity, Iommi built a sound on Black Sabbath records like "Master of Reality" that every riff-centered band since has inherited.
