My first unofficial concert was Hendrix at the LA Forum in '69. Unofficial because my uncle and his best friend, who were in charge of watching me (I was 3 at the time) couldn't score tickets. So instead, we sat out in the parking lot with a bunch of other people who also couldn't score tickets, and listened to the sounds eminating through the forum walls. Not surprising, alot of the event was lost on me, but I do remember bits and pieces of it.
