Rob Allen, who is also referred to by Twitter followers as King Rebel, has started the movement called the Robellion. He explains: "It is my effort to reset the tone of the music business. I want to pave a way for true talent and creativity to be noticed. Music has now become packaged and mechanical with the exception of the veterans who have total freedom in their art. The variety of unique voices and character is missing and I'm going to bring that back." Behind the Robellion is his own team, called Team Rebel. He is currently working with producer Donameche "Don-City" Jackson. Together they have made leaked songs "Pressin' Buttons," "Curves," "Wifey Material," "Beat It Up" and "Kill Cupid."
