What a concert!...I knew who these guys were but I had no idea that this concert would change my life permanently which it did...I have never forgetten that show and I can still see Mickey Hart garbbing the mike off the mike stand and smashing it repeatedly onto the the five foot tall gong on a stand...then he would take the mike and scrape it in a circular motion around the gong face making some incredible sounds...an awesome show!!!!!!!!!!!!!!!!!!!!!!!!!!!!
