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.

If not quite his last will and testament, the work now known as Bach’s Mass in B Minor represents a definitive show-reel or sample-book of the Leipzig cantor’s choral and orchestral art. Its complex patchwork of manuscripts dating from different decades only came together for a full public performance in 1859: the year in which Wagner completed Tristan und Isolde. 

George Gershwin called one of his early classic songs, first created by Fred and Adele Astaire, “Fascinating Rhythm”. It was that mesmeric pull that propelled last night’s Royal Festival Hall Concert from the Philharmonia and its principal guest conductor, Marin Alsop.

Does any living composer write better for choirs, or more demandingly when circumstances allow, than James MacMillan? Admirable as it is to have extant words and music for a music-drama, morality play, call it what you will, by medieval pioneer Hildegard of Bingen, her imagining of a soul torn between virtues and Satan is inevitably one-dimensional. MacMillan finds variety and surprises in response to her text at ever turn of this 80-minute epic.

For all its passing British sea shanties and folksongs, Vaughan Williams’ A Sea Symphony does Walt Whitman’s determinedly global-oriented poetry full justice. That “pennant universal” was reflected in two superlative soloists from South Africa and the USA, our national treasure of an Anglo-Italian conductor, an Argentinian chorus director and a raft of international names in chorus and orchestra who just happen to be UK citizens.

It was the sonically adventurous, shiveringly atmospheric cello piece by Latvian composer Preteris Vasks that proved to be the first showstopper of this enjoyably esoteric evening. Dutch cellist Hadewych van Gent began the pianissimo movement of Vasks’ Gramata Cellam by creating a build-up of whistling harmonic effects on the A string, followed by a yearning feather-light improvisation in the cello’s upper registers that suddenly plunged vertiginously bass-wards.
