Josh Zickert, aka JZ Radical, is a professional skateboarder and owner of the Natural Koncept skate brand. He has managed to carve out his own piece of skate history, primarily for his willingness to throw himself off just about anything. For further proof of such claims you need look no further than his parts in the Natural Koncept videos "Creepin' For Life", "Ghetto Blaster" and "Illegitimate Bastard Child".
Although he has spent time in LA, Japan and Russia, JZ is best known for his work in the streets of New York. In 2009, he even released a series of shorts for MTV2 titled "Skate Life" that followed the life and times and his friends in the streets of NYC.
