Ying Yang Twins

ATL duo Kaine and D-Roc bring the booty-inspired party anthems over devilishly catchy production. Speedy beats, freaky keyboards and ample whistling keep the clubs crunk while they sound off on sex-hungry ladies with tight assets and loose morals. "Whistle While You Twurk" hit No. 1 in the spring of 2000, and their debut album Thug Walkin' was released a few months later. Alley ... Return of the Ying Yang Twins dropped in 2002, followed by their third LP, Me and My Brother (which spawned the mega-hit "Salt Shaker") in late 2003. The Twins' highly anticipated fourth album, U.S.A. (United State of Atlanta), hit the streets in the summer of 2005, propelled by the lead single "Wait (The Whisper Song)." They followed U.S.A. with fifth album Chemically Imbalanced in 2006. That effort was a commercial disappointment, generating a fraction of the previous album's sales and failing to produce a hit single. Afterwards, the group went on a short hiatus, returning in 2008 with the mixtape Official Work.
