Noise

Luigi Russolo, the first noise musician. Maybe. All the coolest noise artists have posters of him or his art on their walls.

Noise is precisely what it says it is: noise. Musically, that means using noise - those sounds that would normally be unwanted or unwelcome in production - in the creation process. For validation of the form as an authentic art, or just to prove you're straight legit, cite Dada, Surrealism, Fluxus, and a few of your favourite contemporary artists as influences.
