Laurel Canyon in the '60s and early '70s was a magical place where musicians gathered to create much of the soundtrack to those times. The Doors, the Beach Boys, Frank Zappa, James Taylor, Carole King, Joni Mitchell and more lived and jammed together here. But the scene had a dark side. Many didn't make it out alive, and many of those deaths remain shrouded in mystery. Far more integrated into the scene than most would like to admit was Charles Manson and his infamous Family. It also seems these colourful characters all coexisted alongside a covert military installation.
