The New Fury has a great article about the do's and don'ts of being a local band. We'll say this, good bands spend more time writing/playing music than spamming people on FB asking you to check them out.
Printing out flyers and posting them around everywhere might not be in vogue anymore, but it should be. In fact, it should be a priority. If you want people to know who you are and you’re not posting flyers, you don’t have much excuse for empty shows.
Don’t complain about where your band is on the lineup. Be thankful you’re playing at all.
