Here’s a great video by DJ Pain1 talking about how to get music fans and get those fans to support your music. In the video he talks about getting fans first then ask for support later and not the other way round.
I believe it’s a good concept instead of demanding support while people don’t know who you are or never heard your music. Build a good music fan base 1st then you can ask for support.
That way you become the kind of artist that people want to support not the kind of artist that is always asking for support and not getting any. Watch the video to get more detailed info from DJ Pain1.
