Following the release on an independent album titled United We Stand, United We Fall, the duo were introduced to fellow rapper Ludacris when he moved into their College Park apartment complex whilst he was acting as a disc jockey: after he took an interest in Playaz Circle, he began to record several songs with the group, playing some of them on his radio station.
