Konrad Wissmann, born on March 17, 1984, in Hamburg, Germany, is a German singer-songwriter and record producer. He began his musical journey with early training in piano, drums, and vocals, supplementing his formal education with self-taught skills. After graduating from the Rudolf Steiner School Hamburg-Wandsbek, Wissmann studied at the Hamburg School of Music, culminating in a performance in Franz Wittenbrink's Café Amazonien revue.
In 2006, Wissmann co-founded the band Ruben Cossani with Michel van Dyke and Leonard Valentin Lazar. The group released three albums: Tägliche Landschaft (2008), Alles auf einmal (2009), and Zu gut für diese Welt (2012). Following a farewell tour, the band disbanded. Wissmann's solo career began with the release of his album Parole in 2013.
