Everyone’s aware that the band Tool regularly reference occult themes and imagery including Thelema in their stage set, lyrics, album artwork etc. Drummer Danny Carey has an extensive collection of Crowley first editions. He’s also got a new book out. His merch page says:
“The specialty printer recently finished and delivered DANNY CAREY’S coffee table-style book entitled “REMEMBER THE FUTURE.” Along with Danny’s essay on collecting vintage synthesizers, the limited edition hardcover contains wonderful glossy full-color photos (by Duncan Blake) of Danny’s impressive collection of synths (many being modular behemoths!), electronic percussion and related electronics. The book also contains articles by synth experts and historians, including BRIAN KEHEW, JACK DANGERS, DARREL JOHANSEN, CHRIS PITMAN and PETER GRENADER. Besides editing the book (with assistance by Greg Taylor), I (Blair MacKenzie Blake) have also contributed a few articles about my own experience with analog circuitry.”
