You're a musician (or even a label). You have your voice, vision, aesthetics. You have some music recorded, or at least composed and honed. What next?
Here's our quick-and-dirty hit list of possible promotional directions:
team up with other artists/labels and start a Drip.fm subscription offering;
make sure you are collecting email addresses on the front of my website and social media pages, I'd give away a free album (maybe a live one or an EP of special songs) on Noise Trade and a different offering on my own email list
I'd test out issuing a single on Spotify (but not the rest of the album; use a single that you think would be connected to another popular artist's sound within your genre/style)
turn on YouTube monetization
do cover songs on YouTube
ask fans to submit videos of my songs on YouTube
get a publisher
get a sync representative and write some songs specifically for use in commercials
master your backing tracks/instrumentals for sync purposes
have a SoundCloud account and engage fans there
have a weekly gig in your home market inviting guest artists from other towns as often as possible to play on stage with you
stream your standing gig to fans across the globe via Stageit or Concert Window and make additional income.
