2)Scha Dara Parr (スチャダラパー) is a three-member Japanese hip-hop group that debuted in 1990, consisting of two MCs (Bose and Ani) and one DJ (Shinco). In comparison to American gangsta rap, Scha Dara Parr lack the hardcore machismo attitude. When pushed to describe the rebelliousness of their music, the group commented that many of their songs are simply fragments of conversation without polite words. The group is best known for their 1994 hit single, Konya wa Boogie-back (今夜はブギー・バック, Konya wa Boogie-back?) featuring Kenji Ozawa (小沢 健二, Kenji Ozawa?), which attained sales of over 500,000 units. The song is based on samples from En Vogue’s 1992 single, Give It up, Turn It Loose. Read more on Last.fm.
