Exactly half a century ago, Semyon Bychkov fled the USSR for the United States as he sought to swap tyranny for liberty. Last night, in a world that feels utterly different yet even more terrifying, the great conductor turned the stellar talents of his Czech Philharmonic Orchestra to the music of Dmitri Shostakovich: both a victim, and a troubled celebrant, of the searing Soviet history he endured.

To watch Mahan Esfahani play the harpsichord is to watch a philosopher at work. While there’s often playfulness and shimmering levity you can feel the thought behind each note. The Iranian-American’s passion for the harpsichord began when he was nine – the moment he heard it on a cassette his uncle gave to him when he was visiting Iran, he knew he wanted to spend his life devoted to the instrument. In a Guardian interview he once described it as the “posh, pretty boy in prison.

A cello concerto received its UK premiere in Manchester last night – almost 100 years after it was written. It’s by Maria Herz, a German-Jewish composer who had to leave her native land in the 1930s and whose work has remained almost unknown until quite recently.

Raphaela Gromes has championed this concerto, giving its German premiere last year, and she brought it to Britain with the Hallé and Alpesh Chauhan (main picture).

Mezzo-soprano Helen Charlston just gets better and better, both as singer and as actor. Last night’s recital at Temple Church had an unusual and wide-ranging programme – consisting of a first half hopping through the centuries, followed by a complete performance of Schumann’s “Kerner-Lieder” cycle.

Last night was the first time I had heard the 12 Ensemble, a string group currently Artist-in-Residence at the Wigmore Hall, and I was very impressed, both by the standard of the playing and the enterprising programming. This gave regular audience-members a little of what they’re used to (a chunk of Brahms) and a decent portion of what they’re not.

At the age of 83, Martha Argerich contains more personality in her little finger than many people do in their entire bodies.

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.
