Clarence Holmes (born April 1968 in Philadelphia, Pennsylvania), better known as Ready Rock C, is an American Hip hop record producer, beatboxer, rapper, and a record producer. He is best known for his early career with Will Smith and DJ Jazzy Jeff, then known as DJ Jazzy Jeff & The Fresh Prince. According to Holmes, he left the group in 1990 because Smith "wanted the spotlight all to himself."
Holmes sued Smith and Townes in 1999, claiming he was owed one-third of the group's profits. The case was dismissed because the statute of limitations had expired.
