This is the third volume in Bournemouth Symphony Orchestra’s well-received Prokofiev series with music director Kirill Karabits. The Fourth Symphony in the original version, played here, is hardly known. Written in 1929 and based on his Diaghilev ballet The Prodigal Son, this early effort has a lightness which Karabits compares to a suite, the style direct and unfussy. (The revised version, Op 112, dates from 1947 and is considered a separate work, though some material overlaps.) In the Fifth, written in 1944 at the height of the Nazi invasion of Russia, Prokofiev keeps any narrative oblique, the mood unexpectedly optimistic. The BSO and Karabits capture the shadows and sparks superbly: they perform No 5 at the Proms on Monday 10 August.
