Bach specialists like to explain that the second book of preludes and fugues in The Well-Tempered Clavier, composed around 1740 and thus almost two decades after the first, draws on more of the fancy and daring “modern” music of its time than its more traditional predecessor. Yes, but there’s modern and there’s modern. I don’t think the scholars have yet argued that, among the ear-stretching range of moods and effects encompassed across these 24 pieces, comes a spooky anticipation of Seattle grunge.

Winterreise brings out the best from Ian Bostridge, and the worst. His dedication to understanding and communicating its complex and harrowing text is everywhere apparent, and this was an emotionally draining evening.

“What is it about Mozart?” wondered the legendary pianist Sviatoslav Richter, pointing out the composer's frightening demands of accuracy and lucidity. Even though many pianists today command technique to spare, a Mozart fear factor tends to keep his sonatas off recital programmes.

In the right hands, the music of the various Viennese Schools can still sound almost startlingly original. Imogen Cooper’s are very much the right hands, containing a rare, refined artistry that only continues to grow with the years.

Singing satirist Anna Russell placed the French chanson in her category of songs for singers "with no voice but tremendous artistry". Mezzo Karen Cargill has tremendous artistry but also a very great voice indeed, a mysterious gift which makes her one in a thousand, and also rather good French (put that down to Scotland's "Auld Alliance, perhaps).

Reaching for philosophical terms seems appropriate enough for two deep thinkers among Russian pianists (strictly speaking, Kolesnikov is Siberian-born, London-based). In what Kant defined as the phenomenal world, the tangible circumstances, there were equal if not always predictable measures of innocence and experience in these Wigmore recitals two days apart.

Matthias Goerne has an exceptional ability to sustain evenness and legato through a vocal line. His breath control and his tone production are things to be marvelled at. He is able to function at impossibly slow tempi, and to make an audience hold its collective breath in admiration. The problem comes when he performs a recital programme which sets out to prove that point. Again and again. All evening.

The Brahms violin sonatas make a perfect spring evening recital. The Second and Third were inspired by a summer retreat, but all three are light, bright and with direct melodic appeal. Violinist Alina Ibragimova and pianist Cédric Tiberghien conveyed that carefree spirit perfectly, the long melodic lines simply but elegantly shaped and the accompanying textures always carefully calibrated.

Frederic Rzewski marked his 80th birthday with a visit to the Wigmore Hall, for the premiere of his aptly titled Ages.

Ruthless Jabiru is an all-Australian chamber orchestra based in London. It is the brainchild of conductor Kelly Lovelady, who in recent years has geared the ensemble towards political and environmental concerns. Previous projects have highlighted environmental damage in central Australia and the campaign to end sponsorship by oil companies in the arts sector.
