I have been to literally dozens of shows which subsequently ended up on YouTube, including lots of Grateful Dead shows, and the US Festival's (1982/83), which were 3-day concerts featuring tons of bands:
The line-up for the 1983 US Festival was even more awesome:
Thank you Steve Wozniak...RIP Bill Graham.
Tickets were $20 a day, but I got in free since I was working for a radio station back then (KOME-FM, the cum spot on your dial)...
I've also attended several concerts made into LP/DVD's, such as Scorpions: Tokyo Tapes, Judas Priest: Unleashed in the East, Bob Dylan at Budokan, and Neil Young and Crazy Horse, "Live Rust" (recorded in San Francisco):
