People have wanted to know ultimately why did Russell Simmons and Rick Rubin split up. Rusell explains to DJ Vlad that they began working on different projects and focusing on other artists. Simmons says he started pulling away gradually as he began to balance other business ventures. Russell Simmons also says he doesn't buy in to rap beef, and he's never had a rap beef. Simmons said artists always get mad but he's not scared of anyone on this planet. We have to wonder are there some old sealed up stories of Uncle Rush getting popping back in the day. Maybe not as he says he doesn't believe in violence.
