Who is the Devil? As a longtime rock and metalhead, I've heard hundreds of songs trying to answer that question, and the thing that strikes me most is how varied those answers are. As an artist, the Devil is whoever you need him to be, a symbolic chameleon taking whatever shape best fits the song. He's one of our most ubiquitous folklore characters, as slippery as he is powerful, and to better understand him, Polyphonic and I are turning our attention to one of the most definitive depictions of the Devil in rock: Sympathy for the Devil, by the Rolling Stones.
