In the works of Krzysztof Penderecki, the cello occupies a special place, being the main protagonist of numerous chamber and orchestra compositions of this outstanding composer. This CD, which continues the series of Krzysztof Penderecki's chamber music, was devoted entirely to cello, as a solo instrument and as a multiplexed composition. The next compositions on the record illustrate the richness of the artist's work, which in the long-term process of searching and improving his musical language reached both the avant-garde and the old epochs. So we will hear the full sonoric experiments of Capriccio per Siegfried Palm, referring to the tradition of Baroque and Romanticism. Suité, virtuosic and lyrical compositions of Agnus Dei, in a word full of palette of cello artistry and expression. Everything is performed in full concentration of performance by Jakob Spahn, a young German cellist, whose chamber music has accompanied the most prominent Polish virtuosos of this instrument.
