On July 4, 1992, I saw Sonic Youth at SummerStage in Central Park. Sun Ra and his Arkestra opened. I remember SY being as frenzied as I'd ever seen them as they played a Dirty-heavy set. (The record was just about to be released.) I don't remember much else, except that I loved every minute of the afternoon. (No need for all the details!)
There is a bootleg release of the show with:
Teen Age Riot
Youth Against Facism
Orange Rolls, Angel's Spit
I couldn't find any video from this 1992 Central Park show. But I did come across Sonic Youth playing "Kool Thing" in Hultsfeld, Sweden, on June 14, 1992 (Close enough!):
By the way, as you may know, Sonic Youth plays later today with the Feelies at Battery Park.
Updated: This week's issue of Time Out New York featured the following line prominently displayed on its cover:
Yes, Sonic Youth was a free event. But you needed to get your tickets in advance. Inside the same issue, you'll see in two places that, although it was free, you weren't getting into the show. SOLD OUT.
Guess no one told this to the person writing the cover lines.
