Over the last couple of decades, the idea of indie rock has evolved. People a certain age might immediately think of REM’s “Radio Free Europe” as their initial reference point.

Fast forward to today and the term encompasses far more that its jangly guitar roots. Now, anything can be indie, and it certainly doesn’t have to be rock. One look at the countless rappers and electronica artists on SoundCloud confirms that.
