John Constantine is, and has always been, a magician of the highest caliber—who doesn’t need additional training from any highbrow magician, thank you very much. Sensing an opportunity for independence, Constantine falsely accepts an apprenticeship in the United States to instead become the lead singer of his best friend’s punk band, Mucous Membrane. When the band begins to dabble in magic, a complicated spell gets out of hand… and the disastrous consequences might be more than Constantine can handle. -- Amazon.
