Dzieła Wszystkie = Complete Works - Sonata Na Fortepian I Wiolonczelę G-Moll, Op. 65 / Sonata Na Fortepian C-Moll, Op. 4

This recording was released by Polskie Nagrania Muza as part of a significant mid-20th-century initiative to document the complete works of Frédéric Chopin. Released under catalog number XL 0081, this pressing features the collaboration of cellist Kazimierz Wiłkomirski and pianist Maria Wiłkomirska, both prominent figures in Polish classical music during the post-war era. The selection includes Chopin's Sonata in G minor, Op. 65, which was the final work published during the composer's lifetime, alongside the early Sonata in C minor, Op. 4.

The design of the record sleeve reflects the aesthetic of the Muza label during the 1960s, typically characterized by stark, formal typography and minimalist photography intended to emphasize the scholarly nature of the collection. Kazimierz Wiłkomirski, known for his dedication to pedagogical and performance excellence, was instrumental in bringing these challenging chamber works to a wider audience. The release was received as an essential contribution to the Polish national heritage, providing a definitive interpretation of Chopin’s chamber repertoire within the context of the socialist-era recording industry.
