This fabulous five disc set is replete with some of those old Stokowski warhorses all recorded in absolutely mind boggling Phase 4 sound, overblown perhaps but astounding for its time. Decca's remastering is absolutely magnificent and the discs are jam packed with almost six hours of music. This is another fine memorial to a great conductor who remained astonishingly vital until the very end of his life.

Angela Hewitt has applied the same intense study to Chopin's Nocturnes and Impromptus as she does to any composer's keyboard works. The result is a set of pieces lovingly played and appreciated, with personally felt emotion. The most outwardly emotional displays, as in the Nocturnes, Op. 15, are never wildly loud and always return to an introverted state afterward. In the Nocturnes she uses little touches of rubato so frequently as to almost stretch the melodies out of shape, as in Op. 9/1, but she plays many of the Nocturnes a tick faster than other pianists so that they stand up to that kind of manipulation better, and she never slows down to fit in ornaments. Her ornaments always fit right into the melody, both in her timing and her phrasing, and are feathery soft.

Passion rather than insouciance is Pires’s keynote. Here is no soft, moonlit option but an intensity and drama that scorn all complacent salon or drawing-room expectations. How she relishes Chopin’s central storms, creating a vivid and spectacular yet unhistrionic contrast with all surrounding serenity or ‘embalmed darkness’. The con fuoco of Op. 15 No. 1 erupts in a fine fury and in the first Nocturne, Op. 9 No. 1, Pires’s sharp observance of Chopin’s appassionato marking comes like a prophecy of the coda’s sudden blaze. Such resolution and psychological awareness make you realize that Chopin, like D. H. Lawrence, may well have thought that “there must be a bit of fear, and a bit of horror in your life”. Chopin, Pires informs us in no uncertain terms, was no sentimentalist.

Esteemed for almost 60 years as one of the greatest Chopin interpreters, Maurizio Pollini confirms his preeminence with this 2017 release on Deutsche Grammophon, and offers his first all-Chopin disc since 2012. Chopin's late works were composed between 1845 and 1849, and include the Barcarolle in F sharp major, Op. 60, the 3 Mazurkas, Op. 59, the Polonaise-Fantaisie in A flat major, Op. 61, the 2 Nocturnes, Op. 62, the 3 Mazurkas, Op. 63, the 3 Waltzes, Op. 64, and the Mazurka in F minor, Op. Posth. 68, No. 4; they are notable for their harmonic richness and freedom of melodic embellishment, characteristics that made them especially influential among his Romantic contemporaries. Pollini's fluid phrasing and control of expression and dynamics have always given his performances sophistication and a feeling of balance, though these are engaging renditions that are far from cerebral or clinical, claims that critics have sometimes laid at Pollini's door. Yet listeners can hear for themselves how polished and deeply felt these performances are, and appreciate the artistic wholeness of Pollini's conceptions, from the elegance of the "Minute" Waltz to the sublime melancholy of the posthumous Mazurka in F minor. Highly recommended for fans of great piano music.

Maria João Pires “shapes and colours every phrase, and with immaculate taste, and she makes sure the phrases end as eloquently as they begin,” wrote Gramophone in 1974. “She conveys not just the details but the relevance of every note to the whole … Best of all, she communicates everything she has discovered about the music, and it is worth having.” This Portuguese pupil of Wilhelm Kempff, Pires was one of the artists who defined the Erato label in the 1970s and 1980s. This 5-CD box gathers together the recordings she made over the period from 1976 to 1985 and it reflects the consistent focus of her repertoire, with its special emphasis on Austro-German composers of the Classical and early-Romantic periods. Embracing solo works, piano duets and concertos, it contains works by Mozart, Schumann, Beethoven, but also by Bach and Chopin.

Pollini's traversal of Chopin's 19 Nocturnes (he leaves out the pair of posthumous ones) is one of his finest recordings in years. His long-lined yet detailed performances are comparable to the very different ones that have long stood at the pinnacle of recorded sets. Not as serene as Artur Rubinstein's, not as philosophical as Claudio Arrau's, nor as warm as Ivan Moravec's, Pollini's interpretations have their own allure. One is the way he shapes the melodies with a natural flow enhanced by his tonal beauty, less lean and streamlined than his usual way with Romantic music.

It is grand to hear novice players so successfully take on three of Chopin's chamber pieces, the Cello Sonata, Piano Trio, and Grand Duo for cello and piano. There have certainly been great recordings of these works in the past – one thinks immediately of those by Mstislav Rostropovich and Jacqueline du Pré – but the energy, enthusiasm, and sincerity that cellist Andreas Brantelid, pianist Marianna Shirinyan, and violinist Vilde Frang bring to this music more than justifies preserving their performances. Brantelid has a big but nuanced tone, an elegant but impressive technique, and an obvious affinity for the music, and he is well-matched by Shirinyan's polished technique and empathic accompaniments and Frang's easy virtuosity and lyrical interpretation. The ensemble is poised but comfortable and the interpretations are cogent and compelling. Captured in close but smooth digital sound, these performances deserve to be heard by anyone who loves this music, or great chamber music playing.
