Successful gigs are not about big gestures but about a combination of small things that get a few people there. This is a list of small things you can do to get an extra 10 people to come to your gigs. The more things you do and the harder you work, the more chance you have of playing to a decent sized audience. Marketing people say that people need to see your band name nine times before they will take an interest in your music, each item on the list is an opportunity to do this.
Some really great points are made here.
Point number 2 is especially good 🙂
