Van Morrison - "Cyprus Avenue," 1970
I saw this on TV when I was 13 and it hit me harder than Iggy, even, because this guy looked like he was just _out there_. Absolutely riveting performance. Watch it fast before Youtube takes it down.
ADDENDUM: Watching Iggy explode out of himself was exhilarating, but Van appeared to be seething inside himself, which was scarier. I saw him in Austin in '79 and was more affected than I expected to be; he seemed to be tapped into some deep well of spirituality, like Patti Smith when I saw her in Dallas circa Y2K. My Van of choice has always been Astral Weeks (and Them Again), but friend ig calls Veedon Flece "undeniable," so I guess I'm going to have to try and hear that.
FURTHER ADDENDUM: Nervebreaker/Big Gun Mike Haskins pulled my coat to this, which just moved to the top of my wish list.
