Four succeeding generations of St Petersburg's finest - Glinka, Balakirev, Glazunov and Shostakovich - are represented on this highly entertaining disc of chamber music, played with style and verve by the London Conchord Ensemble. Chief among the delights is Glazunov's string quintet in A minor, a gloriously carefree and sunny piece, written when he was 26. Dmitri Shostakovich was only 17 when he wrote his Trio No 1 in C minor, but it already has some of the hallmarks of the great man to come. (He was Glazunov's pupil and his father took huge risks supplying his alcoholic teacher with illicit vodka from state supplies.) The final track is a rare treat - the only surviving movement of Balakirev's Octet opus 3.
