…some of the Sonata's radical harmonic language is present in the elusive left-hand Improvisations written in 1918 for Douglas Fox, who had lost his right arm in the trenches. Wass's deeply felt and finely shaded accounts of these pieces, displaying an admirably wide range of touch and dynamics, are probably the best performances on the disc.

[Ashley Wass] plays the Piano Sonata with an expressive rubato that indicates complete understanding of the language and phrasing, a teasing glow in the slow movement and a sense of anxious searching in the finale.
