Poniatowski’s music became lost in the mists of history. It is good, therefore, that nowadays it has become the subject of research by the musicologists Irena Poniatowska and Ryszard Daniel Golianek as well as an object of interest for performers. It is good that artists take it up in their interpretations and bring it back to the listeners. Words of gratitude are due both to the Polish Music Association for presenting Poniatowski’s works during the Festival of Polish Music in Krakow and to the organizers of the English premiere of Mass in F Major at Westminster in London in 2015 led by Dr. Marek Stella-Sawicki. Prince Poniatowski was born in Rome in 1816 and in 2016 we celebrated the 200th anniversary of his birth. “On the eve” of this symbolic occasion, his Mass in F Major received, thanks to Maciej Jablonski and Sebastian Perlowski, a new symphonic life.
