Rock also gets deep into some characters on REBEL SOUL, starting with "Mr. Rock n Roll," a dynamic production piece that doubles as a history lesson, or what Rock calls "a journey through music." "It's just saying how soulless records are now, so how about this -- right in your face," Rock explains. "This guy's dad was a roadie for REO Speedwagon in the 70s and his mom was a high-priced call girl in Hollywood, and he was a product of that. That's why he's got eyeliner on and a big sequined suit. It's a Captain Fantastic, Ziggy Stardust kind of thing." Then there's "Cucci Galore," a return to rap-rock roots with hot tubs, leopard-skinned Lamborghinis, edible bikinis, a slinky guitar line, Public Enemy's Flavor Flav on board for quality control -- and yet another Rock persona, Bobby Shazam.
