Ying Yang Twins

The Atlanta crunk duo of Kaine and D-Roc (Ying Yang Twins) may be better known for their collaborations (the singles "Get Low" and "Salt Shaker" with Lil' Jon, Britney Spears' In the Zone album, their Chemically Imbalanced album with Wyclef Jean as producer), but the pair's latest album, A.T.L. Holes (set for release in November, according to the band's Web site), sees the YYT take off in a more independent direction, but still brims with club hits like "Freak" and "Wham Boom Bam." And the collaborative circle keeps getting bigger: The Ying Yang Twins' new video, "Drop," was produced by Isaac "Ike Dirty" Hayes III, son of Isaac Hayes.
