Jiří Korn began his music career with the rock band Rebels in its 1967 establishment. The group disbanded in 1970; one album, Šípková Růženka, was released during this period.
In the early 1970s Korn joined the band Olympic. He also became a solo artist and released his first album LP 01. His single Yvetta (1972), written by Karel Svoboda, became his first solo hit. In 1977 and 1978, Korn was 3rd and 2nd place respectively in the Zlatý slavík music poll of popular Czechoslovakia music artists, which was frequently topped by Karel Gott. Korn performed several tracks with Helena Vondráčková such as "Tančit Prý Je Krásné" and "Slunce". In 1985, composer Michael Kocáb wrote the tracks "Karel nese asi čaj" and "Nejdřív je trénink" for Korn to record.
In 1990, Korn established Krach, a performing arts agency. He played in the Czech production of Les Misérables in Prague's Vinohrady Theatre as Monsieur Thénardier on 1992, a role he returned playing in the Goja Music Hall in Výstaviště Prague on 2003. Korn's 2003 performance in Les Misérables made him awarded the Thalia Awards category of male musical actors. In 1995, he performed in the Czech Dracula musical. Other stage productions he played includes The Count of Monte Cristo (2000), Golem (2006), Carmen (2008), and Jesus Christ Superstar (2010).
