Figure out how you’re going to digitally distribute the album, and a physical CD only release or selling the CD and mp3’s strictly on your website is not the way to go. You need to make your music available everywhere digital music can be streamed and bought, such as on iTunes and Spotify, and the best way to do that is work with a digital distribution company like CD Baby or Tunecore. With that said, I talk to people all the time who then take this one step too far and sign up with multiple distribution companies because they think they are covering all their bases this way. Which they are not. All that does is put multiple copies of the same album on iTunes and the like, which looks silly and can cause unnecessary confusion. And if you plan on working with a PR company to promote the release don’t set the release date until AFTER you have talked with them first.
