I looked a bit, but might have missed it.. I'm hoping this hasn't been done before.. but let's brainstorm some events that were very, very big in the history of rock music.. One that came to my mind was 1974, California Jam.. That was a major thing, with lots of major bands and a huge, even well run event.. Barely anyone ever really mention this.. So what are some major events you can think of, that are generally forgotten.. I'll try to edit them into the OP and make a list
So far
1974 - California Jam
