Think I've mentioned on this board before that the best show I ever attended was Superchunk around 95 or so at the Trocadero in Philadelphia. But I also have beef with Mac & Laura.
In 96, I rode up to NYC to attend CMJ with a friend. Exhausted, we left our stuff in the trunk of his car and crashed in the cramped over-populated apartment of a friend of a friend. We woke up and went down to get our stuff, only to find that the car had been broken into and all of our stuff stolen, including my Superchunk t-shirt. The only thing the thief didn't take? A cassette by The Fall that was discarded in the front seat.
After buying the cheapest possible **** to wear for the next few days (we were broke college students after all), we proceeded to have a blast going to great show after great show. One of those shows was a Portastatic show in the basement of a school or something, and it was really cool, because milling around in the small crowd during the opening acts were both Mac & Laura. In those days, I never passed up the opportunity to shake hands with one of my music heroes, and so I went up to them to say hello. That went well enough so that I decided to regale them with the tragic loss of my prized Superchunk t-shirt. I wasn't necessarily hoping for a kindly offer of a new t-shirt, but it sure would have been a nice gesture. Instead, Laura just looked at me while Mac only offered a weak, "Man, that sucks!" Then they turned around and walked away.
I also once experienced a similar yet more withering and comical dismissal from Kim Gordon & Thurston Moore, but that's another story.
