This 30-year-old conscious German MC called Prinz Pi released a true German Hip Hop Milestone in 2006: Orchestral production, 52 tracks, and stories about the fairy tale corporate hiphop industry wrapped up in middle age methaphores". In order to get it, though, you need to speak German & be German.
