To be blunt, find someone who likes your music; someone who believes in what you are doing. It’s easy for a publicist to charge a small band a lot money and not really doing anything, so make sure they dig your tunes, fit your style, and want to be a part of what you’re doing.
Marketing your band
You’ve got your well-crafted original songs in tip-top shape. You’ve learned a selection of covers that are sure to impress, maybe an Ironic boy band/or hip hop song that you’ll do acoustically, or totally rock it out, whichever way, it’ll be sweet because it’s your unique style.
