The Internet pushed underground music above ground. Today, an artist like Diplo is mainstream because of the virality of content. He was just a beat maker before Facebook and Twitter blew up.
Popularity ruins underground art. The reason we get into underground music in the first place is because no one else is listening to it. We discovered it first, built a special relationship with its anonymity.
Yet, the struggle for any explorer is the desire to spread their tastes without tainting obsession with the content. As soon as an artist blows up, some hardcore fans give up and look for something else.
Underground music listeners are just trendsetters, trusted sources of taste. You can’t have it all to yourself and talk about it at the same time. The struggle to make people “get it” backlashes. Thankfully, content is endless and there’s always someone new to discover.
