It's December 6, 1969 and just like that, the 60s were over. It started out great, the West Coast edition of Woodstock. Santana, Jefferson Airplane, The Flying Burrito Brothers, Crosby, Stills, Nash & Young, a 300.000 strong crowd and, of course, The Rolling Stones on the final leg of their US tour. And, of course too, Hells Angels armed with motorcycle chains, sawed-off pool cues and $500 worth of beer, hired to stop fans from climbing the stage. And not in the least due to its proximity to Frisco, lots of bad drugs mixing with that crowd.

“Well, The Rolling Stones tour of the United States is over. It wounded up with a free concert at the Altamont Speedway for more than 300,000 people. There were four births, four deaths and an awful lot of scuffles reported.”

– Stefan Ponek, KSN Radio

Even before a single note had come out of Mick's mouth, someone had punched him in the head. More scuffles, Grace Slick begs the audience to keep their bodies off each other unless they intend love. The Grateful Dead, regular deployers of peaceful Angels security, wisely forfeit their performance. The Stones open their set, the final set of the day. By then, the Angels are far into their $500 beer bounty, and the audience far out of their mind. Meredith Hunter, high on drugs, had brought a gun. And the Angels did what they were ordered to: stop anyone from getting close.
