Campbell v. Acuff-Rose Music, Inc. was a landmark US Supreme Court case on intellectual property in which the court reviewed whether a parody of Roy Orbison's song, "Oh, Pretty Woman," by a rap group violated the Copyright Act of 1976. The court of appeals held that the parody did not constitute fair use, but the Supreme Court disagreed, holding that the commercial character of the song did not create a presumption that the parody violated fair use. What rap group recorded the parody?
