The Laurel Canyon Conspiracy
Laurel Canyon was a mountainous neighborhood in the Hollywood Hills region where some of the biggest folksingers and musicians of the '60s and '70s congregated to live side by side. Artists like the Monkees, the Eagles, the Beach Boys, Joni Mitchell, and Jim Morrison lived there, but there was a dark side to this hippie commune — many people didn't make it out alive, and it's still a mystery why. 

Charles Manson and his entourage were also part of the commune, giving him one of his first tastes of the Hollywood scene.
