Giovanni Zarrella's musical career is a blueprint for those who came of age in the American Idol generation. After finding fame on the German competition series Popstars -- he was a member of the vocal group Bro’Sis for half-a-decade -- Zarrella has since gone solo with a discography that honors his cultural heritage by mixing schlager and Italo-pop. He buoys his affable adult contemporary sound with a parallel career as a television host.
