I'd like to hear if anyone has had any mishaps at a gig/recital/concert playing an instrument other than the bass. A few years ago, I was at the winter band concert. I had recently started the trombone and was still a little clumsey with the slide and the slide lock. During a session where the Jazz Band was playing, I lost my concentration and let go of the slide, having it slip off the instrument, down the stairs and into the audience. It was awful.
