Myra Hess was one of the most important figures in British cultural life in the mid-20th century: the pre-eminent pianist of her generation and accorded “national treasure” status as a result of the wartime lunchtime concert series at London’s National Gallery, which she singlehandedly masterminded through 1,698 concerts between 1939 and 1946.

The second of the Philharmonic’s Boulez-Ravel celebrations (birth centenary of the former, 150^th of the latter) brought Bertrand Chamayou back: after his performance of the G major piano concerto in January, this time it was as soloist in the Concerto for the Left Hand, with Ludovic Morlot on the podium.

At the end of an exhausting week in which Holocaust Memorial Day struck a more urgent note than ever as fascism started tearing through the USA, parts of this concert were bound to hit hard. That they did so to the power of 100 was thanks to the extraordinary impact of Jakub Hrůša, now recognised as one of the greats by British audiences as he waits to take up the full-time reins at the Royal Opera. The BBC Symphony Orchestra burned for him in fullest focus.

There was excellent music making in the Hallé concert in Manchester last night, and there was self-admitted “noise”. Briefly, the two coincided in one work.

Forthright and upright, powerful and lucid, the frank and bold pianism of Leif Ove Andsnes took his Wigmore Hall audience from Norway to Poland (or rather, Paris and Majorca) with a final stop in France. A recital that began with two large-scale Norwegian sonatas – one a remarkable discovery – culminated in the ostensibly remote sound-world of Chopin’s 24 Preludes, part-written on the Balearic island.

Is this the same Roman Rabinovich who drew harp-like delicacy from one of Chopin’s Pleyel pianos, and seeming authenticity from a 1790s grand which may have belonged to Haydn, both in the Cobbe Collection at Hatchlands, Surrey? He clearly cares about the possibilities of any instrument on which he plays, so the natural consequence is maximum sonority on a modern Steinway. Too cultured to deafen, as Beatrice Rana did in this small space, he still compels you to listen to every note.

Beethoven’s renown in his own day was not just as a composer but also as an improvising pianist. He wrote in a letter in July 1819 that “freedom, and to move forward is the purpose of the world of art, as it is of the whole of creation.’

The BBC Philharmonic were right to bill Garrick Ohlsson, soloist in Brahms’ Piano Concerto No. 1, as the main attraction in Saturday’s concert.

The septuagenarian American is a force of nature and an exceptional artist: his playing of Rachmaninov in his last visit to Manchester remains in the memory as an exhibition of mastery. So it was again, in another concerto thick with notes.

Wonders never ceased in Elisabeth Leonskaja’s return to the Wigmore Hall. Not only did she play Schubert’s last three sonatas with all repeats and the full range of a unique power undiminished in a 78-year old alongside a never too overstated pathos, radiance and delicacy; just before receiving the Wigmore Hall Medal (presentation by John Gilhooly pictured below), she also gave us more revelations in the compressed world of Schoenberg’s Six Little Pieces, Op. 19.

If there was ever a time for the inevitable "Rach Three” (piano concerto, not symphony) in the composer’s 150^th anniversary year – and I confess I dodged other occasions – it might as well have come in the fresh and racy shape of Leif Ove Andsnes' interpretation and the equally alert, forward-moving playing of the London Philharmonic Orchestra under a kindred spirit, its principal conductor Edward Gardner.
