"Beats of Freedom" is a captivating film about the birth of rock music in Poland. In the times when life was controlled by the communist regime, music became an extremely powerful phenomenon. The Iron Curtain could not stop rock music, thanks to which young people could find their space of freedom. From the very beginning, Polish rock stood in opposition to the reality. The songs broke stereotypes and formed bonds among people. One particular freedom enclave was the festival in Jarocin, colourfully shown in the film thanks to previously unpublished archival materials.
