Experimental

Experimental is kind of a catch-all term for those who go for unconventional techniques that are noisy and often atonal. Whether they are advanced atonal and aleatoric techniques, or someone just messing around with sounds and ideas, they are definitely trying hard to often not fit in with the crowd. Whether that chaos creates discord or is seen as its own great masterpiece is often up to beholder or to those who appreciate such music that's just a little different then the rest.

Check out these artists who specialize in this style of music.
