Dubbed by wags "the singing secondary schoolteacher" as a result of his often didactic lyrics, German rocker Heinz Rudolf Kunze enjoyed his greatest success in the mid-'80s via the smashes "Dein Ist Mein Ganzes Herz" and "Mit Leib und Seele." Born November 30, 1956, in Espelkamp-Mittwald, Kunze was afflicted with acute bone disease throughout childhood, channeling his limited energy into books and music. He first pursued a career as a writer, earning some measure of fame for short stories including Zu Karla Übers Wochenende and Romanze den 1. During the mid-'70s Kunze began singing with the rock group Provinzriesen, over time learning guitar and piano. In 1980 he appeared at Würzburg's Pop-Nachwuchs-Festival alongside guitarist Mick Franke, so impressing audiences and judges that he landed a five-record deal with WEA. Kunze's debut LP Reine Nervensache followed in 1981. A critical smash, the album earned a series of honors, most notably the Berliner Wecker and the Willy-Dehmel-Preis. His 1983 effort Der Schwere Mut was no less acclaimed, and as his notoriety grew Kunze expanded into other media, penning an essay on American singer/songwriter Randy Newman for Der Spiegel and hosting radio series for NDR and SFB. With the title cut from 1985's Dein Ist Mein Ganzes Herz he scored his first German Top Ten hit, although the album was his last with longtime collaborator Franke, a break that for many fans signaled the conclusion of Kunze's most creative period. The 1986 release of Wunderkinder nevertheless proved his continued commercial viability. The album quickly entered the Top 20, notching the hit single "Mit Leib und Seele," and he went on to receive the coveted Goldene Stimmgabel.
