Most new bands approach the first part of their careers like this: We need to find an audience, but in order to find an audience we have to play shows. If we want to play shows we have to get a talent buyer to book us, but talent buyers are going to want to know we can draw an audience before they’ll ever consider letting us play. It’s a frustrating catch-22.
