Richard McKay leads the Dallas Chamber Symphony in a program centered on structural evolution and string texture, beginning with Górecki’s “Three Pieces in Old Style,” a work rooted in Polish Renaissance and Baroque modalities. Harpist Yumiko Endo Schlaffer then joins the ensemble for Debussy’s “Danse Sacrée Et Danse Profane,” a foundational diptych that explores the contrast between ritualistic and chromatic harmonic languages. The evening concludes with Strauss’s “Metamorphosen,” a complex study for 23 solo strings that serves as a profound meditation on cultural transformation.
