Musicians of Tildes, how do you promote your music?

My band are releasing a new single on the 5th August, another later in the year, and a third early next year. We've released a few tracks already, but we never seem to get much traction when trying to promote them. The band has agreed that a different approach is probably needed, and so we're open to a bit of experimentation. So, musos of Tildes: how do you go about promoting the music you release?
