Heinz Rudolf Kunze is a singer/songwriter and musician from Germany who rose to prominence during the 1980s. Affectionately referred to as HRK, he released his debut album, Reine Nervensache, in 1981, and dropped his breakthrough record, Dein ist mein ganzes Herz, a few years later in 1985. Unlike many pop artists who instantly rise and then fall from the spotlight, Hunze has not only maintained his mainstream appeal throughout the decades, but has actually increased his commercial viability. With over 20 records in his catalog, he has collected a dedicated fan base that continues to grow with each of his releases, including 2007's Klare Verhältnisse.
