So i've been explorin new genres of music, even if the very concept of genre is flawed, but whatever, and i found out "Xenharmonic" music is a style wich employs very unconventional means of creation. And you can look it up to see exactly how because i'm not sure how to explain without copy/pasting, it's really wierd, like it's straight out of Myst or something..
So anyways, a sample;
Less aggressive example ;
Also if you know any other obscure genres, feel free to share and discuss !
