1968 US original. Glossy, NM- vinyl but listed as VG++ due to visible mar on side 2 that does not affect play. Penderecki: Dies Irae (Auschwitz Oratorium) / Polymorphia / De Natura Sonoris is an outstanding album that reflects the talent and creativity of two of the most important composers of our time, Krzysztof Penderecki and Henryk Czyz. The album combines three monumental pieces that showcase the power and versatility of classical music.

The centerpiece of the album is Penderecki's Auschwitz Oratorium, a haunting and emotionally charged composition that was inspired by the horrors of the Holocaust. This powerful work features a full orchestra and chorus, as well as a solo soprano and baritone. The music is dark and intense, and it conveys a deep sense of despair and tragedy. The album also includes Polymorphia, a complex and experimental piece that features a string orchestra and explores the boundaries of sound and structure. Finally, De Natura Sonoris is a beautifully crafted piece that blends traditional orchestration with electronic elements, creating a unique and otherworldly sound.
