Roo'ra

Roo'ra ("Rulla") is Korean hip hop and dance group from 1994–2001. Its name is abbreviation of Roots of Reggae.

Many of the group's albums were the top selling of their time in Korea, with their debut album selling over 280,000 copies. They hold the record of first artist to sell one million albums in the dance and hip-hop genre in Korea. The group also caused significant controversy in 1996 through the discovery of their unattributed sampling of a Japanese track ("Omatsuri Ninja", お祭り忍者 by Ninja) directly in their own song "Cheon sang yu ae" (天上有愛 "천상유애").

This incident raised a heated debate '...about the nature of "Korean-ness" in popular music' and pushed this pointy but long dormant issue to the forefront in the mid-1990s. The group nearly split in 1996 due to the controversy and then finally in 2001 after the release of their final album. In 2008, the group was reunited with Lee Sang-min, Go Young-wook, Kim Ji-hyun, and Chae Ri-na to work on an upcoming album. In the middle of the project, Shin Jung-hwan and Go Young-wook formed a temporary duo group, "Roo'ra Man" and released a single, "The Reason Why I Hate Winter" in December 2008. The single was produced by Lee Sang-min. Roo'ra's new album is expected to be released in July 2009 with "Going Going" as the first single.
