This is mostly a collection of online writings and designed for people who want a hard-cover copy of those things. There are a lot of essays about rock and roll in this book. Stuff about the occult trappings of Led Zeppelin and Black Sabbath. In addition to the obvious rock and roll stuff, like hoodoo in the Blues and Jim Morrison being freaking awesome, there's also stuff in here about Marc Bolan of T. Rex! Super cool.
In addition to the rock and roll stuff, there are essays about rituals, Horned Gods, an extended look at the worship of Aphrodite in the Ancient World, and a crazy store about Dionysus, Jesus, and cheese crackers. Seriously.
