On Thursday, Czech Radio Vltava will premiere the documentary Postscriptum of Bedřich Smetana. Created by Tomáš Dufka, head of the radio archive, the project examines pivotal political and social events, such as the Nazi occupation of Czechoslovakia, through the lens of Smetana's music, which left a powerful legacy after the composer's death. The documentary uses dozens of newly discovered materials from the Czech Radio archive, among other sources.
