I had a chance to read ten pages of my morning coffee.
You write well - smooth, clear and concise. That being said, I didn't find the premise compelling.
I've seen this premise play out too many times to be interesting - down trodden band/singer performing at dives and then one day the mysterious manager's in the crowd - hands them the card. So while I found the writing solid, the story wasn't original enough to spur me on to read more.
Best of luck with this
