In the summer of 1976, Billy Baal and his bandmates gathered to record the follow-up to their smash hit debut album BAAL. What emerged from those sessions was a Grammy-winning classic that would change the face of rock n roll, and a legend of sex, drugs, ego and hedonism to rival any the music industry has ever seen.

Within a year, Billy’s copious drug use, torrid affairs with both women and men, his tumultuous relationship with bandmate Sophie Barger, and rumours of his involvement in a tragic drowning had torn the group apart. Nearly four decades later, the mad genius frontman whose band bore his name is all but forgotten, but his impact on American pop culture lives on. This is his story.
