First held as a national event in 1979, the Adam Didur Competition became international in 2004.
This year’s 5th edition coincides with the 150th anniversary of the birth of Adam Didur, a famous Polish bass singer who performed at prestigious venues such as the Metropolitan Opera in New York and La Scala in Milan.
Critics praised Didur's sonorous, dark-timbred voice, suited for both Rossini and Wagner roles.
After retiring, he returned to Poland and founded the Silesian Opera, which debuted in June 1945 with a production of Moniuszko’s Halka.
Didur died of heart attack on January 7, 1946, after collapsing during a singing class at the Music Conservatory in Katowice.
