This was the last concert performed at the Terrace Ballroom before the need for yet another parking lot in SLC. I was only 19 and too young to get in so my friend Chandler snuck me in the back door. Zappa & Vai played guitar for over 1 hour without saying a word. It was loud it was real, the audience watched in amazement. They took a break and when Zappa returned he broke into his normal comic self. An absolute blast from the past. Unforgettable.
