"Wizard rock"—music based on the Harry Potter series by J. K. Rowling—is an idiosyncratic subgenre, with band names like Harry and the Potters, Draco and the Malfoys and The Whomping Willows. Drawing on input from insiders and fans, and interviews with more than a dozen wizard rockers, this book explores the history and aesthetics of the movement. An appendix lists dozens of popular bands, members and discographies: a must-have for fandom scholars and wizard rock devotees alike.
