In the very same summer that I had a musician not show up to a gig, I made a nearly-fatal error that could have cost my string quartet its reputation. I lost a bride's playlist the week before her wedding.
It was pretty early on in my string quartet's history. We didn't quite have our act together as far as organizing setlists. For us to complete a playlist for a wedding, I would have a series of back-and-forth email conversations with the couple.
