Fler, a stage name for German rapper Patrick Losensk, serves as the CEO of Maskulin Music Group. Fler's collaborations with Bushido helped establish his reputation in the rap scene. In October 2002, they together released the album Carlo Cokxxx Nutten. On Bushido's debut studio album, Vom Bordstein bis zur Skyline, which was released in July 2003, Fler had five featured roles. On May 1, 2005, Fler released Neue Deutsche Welle, his debut album. "NDW 2005," the first single, featured a sample of Falco's "Rock Me Amadeus." The record was viewed as contentious because of what were thought to be right-wing extremist lyrics.
