Medtner’s sonata is marvellously contoured, very poetic, maybe in its own way comparable to Moiseiwitsch’s playing of the composer’s music. The recording wasn’t good for its time. Glazunov’s E minor sonata is despatched with elegance and lyric distinction but also a great reserve of dynamism as well. His marshalling of the peaks and troughs of the second movement Scherzo is a mini master class in itself though you will be thrilled by the huge dynamic curve he sculpts in the finale.

Prokofiev, some of whose sonatas he appeared to appropriate and ‘own’ is represented by the Second. Gilels brings tremendous clarity to it, whilst simultaneously managing to extract a full panoply of tense lyricism. He conjures up pungent sound worlds with immediate strength, as in the same sonata’s finale—brilliant, crisp and clear.

The morceaux are no less a part of a musician’s arsenal and they are, in the main, heard first in the running order. The Tchaikovsky is lovely, though there’s a bit of ingrained wow on the disc. His Rachmaninoff Prelude is brasher and bigger than his later way with the music, when he took it more cautiously. The result is that finer precision suffers a little in this truly galvanising exercise, but few will mind when the results are so vital.

Excellently transferred, as one would expect, this is another well curated selection.
