Well, in my humble opinion I think it’s best to start thinking about what you want to achieve with promoting and how to promote after that. I’m no promotion specialist, but if you want to go on stage with your band, the first thing that comes to my mind is to start advertising in the neighborhood. Other things that come to my mind are trying to get some attention in the local newspaper, use social media and post your tracks online on all the sites you can find. If you aim to get signed, I guess if you’re good enough you will get noticed eventually. 🙂
