The second installment of Antal Zalai"s complete Bartók violin edition centers on the monumental Sonata for Solo Violin. The work is a landmark of the 20th century where contrapuntal and fugal writing, folkloristic elements, and the unique harmonic and rhythmic language of Bartók fuse into a work of intense expression. The 44 Duos for Two Violins serve as a foil for the Sonata, performed with wit, irony, and folksy color by Zalai and Valery Oistrakh.
