It's interesting that you mention heavy metal music, because I've noticed since I've been back in the EDM scene that for whatever reason a lot of heavy metal/rock culture is seeping into the EDM culture. Headbanging, for one. Mosh pits, as well. It fascinates me that even some rock artists are venturing into EDM stuff too.
I'm heading to an EDM festival in a few days, so be on the lookout for new content on The Dancing Dreamers soon! :)
