The Piano Quartet by much-admired Latvian composer Pēteris Vasks is one of his longest and most imposing chamber works. Unfolding with inexorable expressive force, it utilises dance-like motifs and folk-inflected themes throughout. The pieces by Lithuanian composer Arvydas Malcys form a cohesive sequence akin to a three-movement piano quartet in which specific sound effects, emotional power and colourful textures are in perfect alignment.
