Malta Foundation invited donGURALesko to prepare a special rap song entitled „20”, which is based on an essay by Professor Snyder „On tyranny. Twenty lessons from the 20th century”. The song will have a video featuring - apart from donGURALesko – Profesor Snyder himself. The video will premiere on 18 May on Liberty Square during Poznań’s Night of Museums. The rapper also recorded „On tyranny” as an audiobook, which will be made available to download free of charge on the day of the concert.
