Think in simplicity. How do I get the attention of a club I want to play? I have dropped off promo, emailed the link on the website and made unreturned phone calls to the person that books the room. Do you hang out in the room? Do you network with bands that play the room? Do you talk to patrons that go see bands in the rooms and give them your music to listen to? Are there outside agents that book the room? Have you made them take a meeting with you? Are you good? Are you persistent? Do you make excuses for your lack of opportunity? Do you talk shit about the bands that do get the gig to others?
You have to immerse yourself into the culture of a room. You must make yourself and your band part of the positive collective that makes up the fabric of the room. If your band is REALLY good, you will get your shot.
