In 1932 English pianist Harriet Cohen commissioned the best of Britain’s composers – Vaughan Williams, Ireland, Walton, Howells – to produce transcriptions of Bach for piano. The result, A Bach Book for Harriet Cohen, is a true document of its time, no less fascinating for its rather conservative contents. Conservative is not an adjective that could be directed at Angela Hewitt’s 20th-century reinvention of the project however. With composers including Brett Dean and Robin Holloway, and works inspired by Bach alongside straight transcriptions, it makes for a joyously diverse programme; last night it proved that it works every bit as well in performance as on the page.

First, an admission. I have a blindspot for the chamber work of Fauré, Saint-Saëns and Ravel. I've tried my best, acquainted myself with the most stirring recordings of the finest pieces, got friends to hold my hand. But I've never been able to shake off the feeling that this French trio are mostly a bit drippy in this repertoire, a bit Watercolour Challenge, a bit I-eat-yoghurt-vote-Lib-Dem-and-faint-a-lot, engaging neither in psychology nor dazzle, all simply treading water. So last night was laser-eye-treatment time. If Steven Isserlis and his clever colleagues couldn't banish my blindness at their Wigmore Hall recital, no one could.

There is an excess about the Wigmore Hall’s Arts and Crafts cupola that lends itself to extravagant musical passions. The mural’s cloudy images may profess to picture music as an abstract creature, but the golden tangle of rays and warmly naked limbs make a rather more human case for its attractions. It was a case matched for persuasive enthusiasm (and significantly bettered for taste) last night by The English Concert and Alice Coote, in a programme of charged highlights from 16th and 17th-century repertoire.

As we take in news of the cuts that the arts will have to absorb, and wait for the Cassandras to start hollering, it's important to remind ourselves of one arts venue that won't be wiping one bead of sweat off its brow as a result of today's announcements: the Wigmore Hall. This season, Britain's finest chamber music venue has a line-up of unsurpassed quality and variety. Yet it does so with less subsidy than any other equivalent music organisation in the country. Cuts in state subsidy do not end quality. They improve it.

Heartfelt birthday salutations to the great pianist first known as plain Stephen Bishop. For a recital in the early 1980s, when he first added the paternal Croatian "Kovacevich", introducing me to late Brahms piano music - Op 117, never more evanescent or troubling since - and the Beethoven Tempest Sonata, an incentive to tackle that work as best I could. For many unbudgeable CDs on the shelves, including the great duo partnership with one-time other half Martha Argerich and late Schubert sonatas.

The first phrase of the first piece by Georges Enescu - silken, expressive, rounded, breathed to perfection - established a very good case for Håkan Hardenberger being the greatest living trumpeter. The rest of his Wigmore Hall recital established a pretty equally watertight case against.

No, not some crazy remake of an Eighties soap featuring various members of the Bach family (though I wouldn’t put it past certain channel programmers to come up with the idea), but the Academy of Ancient Music’s (AAM) new series of concerts, which in a nutshell gives them the chance to perform lots of Johann Sebastian, with two bookend concerts covering the befores and the afters, as it were. Bound to get the crowds in and looks nice on the posters.

Do paws get any mightier than Llŷr Williams's? When not crashing down onto the Wigmore Hall Steinway like a ton of singing bricks, they were digging deep, like strong, nifty moles, foraging for the contrapuntal melodies that lay beneath the topsoil. Williams was made to tackle the beefy German classics on this programme.

Ian Bostridge is one of those artists – Andreas Scholl is another – whose technique is so suited to the recording studio, his recordings so ubiquitously loved and lived-with, that the opportunity to see him perform live has become one of conflict. Suffering from the same malaise as successful pop artists, concert performances inevitably become processed by over-exposed ears as acts of mimicry; studied verisimilitude to a recorded original jostles for validity alongside live creative re-imagining.
