ARNOLD: Concerto for 2 Pianos 3 Hands / Concerto for Piano Duet. Composed in 1951 during a period of almost frenzied activity, the Concerto for Piano Duet & Strings is one of Malcolm Arnold’s finest concertos, full of technical display, melody, contrast & colour. The Concerto for Two Pianos (Three Hands) & Orchestra was written for the legendary 3-handed husband & wife team of Phyllis Sellick & Cyril Smith.
