American pianist Jeremy Denk made his recording debut in 2010 playing Charles Ives’ notoriously thorny yet exuberant and life-affirming piano sonatas. Fourteen years later that album, now remastered, is coupled with new recordings of Ives’ violin sonatas. All composed just before or during World War I, Ives’ violin sonatas somehow reflect the troubled spirit of European music at that time—not only in terms of embracing folk music and dissonance, but also sharing a great deal of harmonic poignancy, bringing to mind at times even the late works of Debussy. Denk here joins forces with violinist Stefan Jackiw, who demonstrates a truly chameleon range of styles and colours to match and reflect the composer’s own wide-ranging and enthusiastic embrace of so many varieties of music. Try the reflective “Largo” of Violin Sonata No. 4 (“Children’s Day at the Camp Meeting”), in which Jackiw’s lyrical playing complements the wild washes of almost incidental sounds from Denk’s piano. Or, for contrast, there’s Denk’s jazzy ragtime in No. 3’s “Allegro”, well matched by Jackiw's playing adorned by a distinctive bluesiness. And Jackiw briefly does a brilliant impression of a ham-fisted drunkard in the central, wild “In the Barn” movement of Violin Sonata No. 2.
