Lol Rahzel is the god father of noise, listen to " if your mother only knew " he beat boxes and sings at the same time ( sings not rap ) then he does a battle with his brother V two dj skribble and slink in a man V machine battle. He breaks out into the four elements. I have also heard him do " wu-tangs chambers track while method man freestyles. This was just noice cut together.
