As far as I know Joyo owns the business. But there is a lot of synergy going on there, everyone that works there doing what they do best to make the final product perfect. You are right the credit should be spread around but I know Joyo well enough to know that it is, perhaps not in print but it actuality. Joyo is good folks unlike many business men he is real quick to give credit where credit is due.
It's not the owners that make the difference, it's the crew! They are the ones there day in and day out getting the job done... just my opinion. Props to Rocco and all the boyz!
