50 moments that changed the history of Rock&Roll

There are probably a lot more, but there are a lot of moments, unforgettable moments. Like:
- ELVIS PRESLEY = loved by youngsters, cursed by their parents, caused by his act.
- BOB DYLAN went ELECTRIC, it must have been a "horrible experience" for Dylan
- THE BEATLES = SGT. PEPPER
- WOODSTOCK 1969 = No comment (August 1969)
- ROLLING STONES = The "infamous" ALTAMONT concert, with performers as Jefferson Airplane, CSN&Y, Santana, Flying Burrito Brothers, and 300.000 people. Grateful Dead was asked to play before the Stones, but they canceled at the last minute.
During the Rolling Stones performance, Hell's Angels By some accounts, the Angels were hired to be security by the Rolling Stones on recommendation from the Grateful Dead for $500 and free beer, they had provided security at Grateful Dead shows in the past without reported violence.
ONE THING having such a crowd = Crowd management proved to be difficult. Many spectators were injured and four died. The ANGELS, where young, no leaders were present, and they became more and more aggressive and violent during the day. They also used sawed-off pool cues in order to control the crowd, or aimed at troublemakers with their bikes at full throttle, causing serious injuries. After one of the Angels' motor bikes was knocked over, the Angels became even more aggressive, even toward the performers onstage. Marty Balin of Jefferson Airplane was knocked unconscious following an altercation with an Angel on stage, as seen in the documentary film Gimme Shelter. That's where the Grateful Dead decided to leave. A guy named MEREDITH HUNTER, 18 years old Afro-American became involved in an altercation with some Hells Angels and drew a long-barreled revolver. It is clear that Hunter drew his weapon before he was stabbed the first time. He was stabbed five times in total and kicked to death.
All this is filmed, the movie's name HELTER SHELTER. I know, a lot of information here, just to show and compare with WOODSTOCK.
That ALTAMONT concert is generally considered as the END OF AN ERA, THE HIPPIEculture..
- LED ZEPPELIN = ruling everything in the 7ties
- SEX PISTOLS
- THE DEAD of JOHN LENNON
