Frankly I'm ashamed of myself that I never knew this existed. As someone in the YouTube comment section said, if cocaine had a voice, this is what it would sound like. Everything about this is perfect, the crazy yells, the yammering about nonsense, the WHEEZY WHISTLE!! It has everything and now I'm on a mission to find more isolated vocal tracks. There's a TON of them out there.
For comparison, this System Of A Down, "Chop Suey" vocal track is so badass I can't stand it. Serj Tankian has an amazing rock voice
