Archival recording of the recital which took place on February 21, 1948 in the Pompeian Room of the Belvedere on the occasion of the 138th anniversary of Fryderyk Chopin's birthday. Raul Koczalski was the student of Chopin's pupil Karol Mikuli. He devoted his entire artistic life to Fryderyk Chopin and considered himself an heir to the Chopin tradition, handed down to him by Mikuli. He left many recordings of Chopin, Bach, Mozart, Liszt, Paderewski, Schumann and his own. The recordings are unique due to sound of "Chopin" Pleyel piano from 1847.
