This definitive work on the occult’s “great beast” traces the arc of his controversial life and influence on rock-and-roll giants, from the Rolling Stones to Led Zeppelin to Black Sabbath. When Aleister Crowley died in 1947, he was not an obvious contender for the most enduring pop-culture figure of the next century. But twenty years later, Crowley’s name and image were everywhere. The Beatles put him on the cover of Sgt. Pepper’s Lonely Hearts Club Band. The Rolling Stones were briefly serious devotees. Today, his visage hangs in goth clubs, occult temples, and college dorm rooms, and his methods of ceremonial magick animate the passions of myriad occultists and spiritual seekers.Aleister Crowley is more than just a biography of this compelling, controversial, and divisive figure—it’s also a portrait of his unparalleled influence on modern pop culture.
