The Armory does ring a bell, so I'm guessing that would be it.
Actually, I just did a quick search and found a FB post by one of his friends reminiscing about it, so yeah he definitely did the Armory show. The friend was claiming that he "helped" my brother which is BS, that guy was really sketchy and never helped with anything. Well he "helped" if he could benefit without having to do anything, so he probably told my brother "yeah that's a great idea"
I never got to see them, I hope its a great show!
