Our first gig was awful. We were playing for a friend of our guitarist. She was having a birthday party and rented out the local municipal building. We got there at the scheduled time and found that the doors were locked, and had to wait around for about an hour before she finally got there. Then I think we had to wait another hour for her to get the key to open the building. It wasn't her fault; the building manager had forgotten to give it to her, or was unavailable (or something like that). By this time, our guitarist/singer was pretty pissed. The drummer and I were just anxious.
I remember I wore these ridiculous plaid bondage pants in an attempt to look punk. I probably looked ridiculous, but got compliments on them, I guess.
We ended up starting about a half hour late. By this time our guitarist was all mad. My mic didn't work and he just said "well, don't use it", not even attempting to make it work through the PA. Then, disaster happened...about five songs in, his Crate amp died, and his dad had to go home and get his back-up (which was a Marshall...should've used that one to start).
We managed to finish the show half-way decently at least. Fortunately, our guitarist has mellowed out a bit after the last three years or so...but I can remember during that first gig thinking "well, this band was nice while it lasted." It's just important to keep your cool and remember that bad stuff happens to everyone, and you just have to work through it. Having a back up plan is important, too.
