JAMES EARLY produced MC HAMMER'S hits like CANT TOUCH THIS, TURN THIS MOTHA OUT and i think LETS GET IT STARTED...
RICK ROCK HAS GOTTEN MORE AIRPLAY THAN ANY BAY PRODUCER I CAN THINK OF. his hit with MARIAH & BUSTA "I KNOW WHAT U WANT" won song of the year for ASCAP and got millions of spins around the world, also, BUSTA'S SONG "MAKE IT CLAP" was a monster on radio and MTV and BET. MASE's song "BREATH STRETCH SHAKE" got tons of airplay, ANGIE MARTINEZ song "IF I COULD GO" was huge out here all over the eastcoast. HYPHY was HUGE all over CALI. not to mention literally hundreds of other songs of his that have gotten spins.
