This piece is often referred to as the Sonata in G minor for 'Cello and Piano because Rachmaninov believed both instruments are of equal importance. This cinematic insight into how two virtuosi - Robert Cohen and Heini Kärkkäinen - rehearse, polish and perform clearly illustrates Rachmaninov's point of view. The piano introduces themes that the 'cello expands and embellishes. The Andante is performed here by Robert Cohen - one of the world's greatest living 'cellists - and Heini Kärkkäinen - an internationally renowned Finnish pianist.
