This year marks the 90th birthday of Krzysztof Penderecki (1933–2020), one of the most prominent 21st-century Polish composers. Sacred themes and texts permeate the creative work of Penderecki, notably in many of his large-scale compositions. This album, performed by the award-winning Latvian Radio Choir under the direction of Sigvards Kļava, encompasses a significant portion of Penderecki’s impressive sacred a cappella choral works spanning five decades, mainly written in Latin. These deeply religious choral pieces have become modern classics in the choral repertoire. The choir’s recent album, featuring choral works by John Cage, earned the prestigious Gramophone Award 2023 for the best choral album of the year.
