Polish jazz traditions go back to 1920s when famous composers like Henryk Wars, Jerzy Petersburski or Artur and Henryk Gold were creating compositions for film, cabaret, and theatre. These traditions are kept alive by Marcin Masecki and Jan Emil Młynarski, the founders of Jazz-Band, performing the interwar jazz compositions. Their repertoire features pieces of unknown swing music, as well as popular tango pieces. The concert pays a tribute to Adam Aston, a celebrated singer, and Henryk Wars, the most important pianist and composer of pre-war Poland. It is a part of the music tour promoting Młynarski-Masecki's second album "Płyta z zadrą w sercu" ("Album with the thorn piercing a heart").
