"i'm talking about my life. i can't seem to get that through to you. i'm not just talking about one person, i'm talking about everybody. i'm talking about form. i'm talking about content. i'm talking about inter-relationships. i'm talking about god. the devil. hell. heaven. do you understand? finally?!"

that's the sound clip that comes before this song. i'm curious as to where it comes from, so if anyone knows, post it.
