Prague’s Semafor theatre was the most significant arts institution in 1960s Czechoslovakia, ushering in a new era against the backdrop of a slow political thaw in the communist country. Semafor was centred on the song-writing duo of Jiří Suchý and Jiří Šlitr and gave starts to a whole generation of enormous and enduring pop stars. Top Czech music writer Pavel Klusák explores the theatre’s great decade in his brand new book Suchý and Šlitr: Semafor 1959–1969 – and shared his insights at our studios in Vinohrady.
