French-Canadian pianist Hamelin has the technique and the stamina to play anything, which is why the note-crazy, obsessive “Night Wind” Sonata of Nikolay Medtner buzzed around at the heart of his recital. But between the proud resonance of its many climaxes and the distant voices he showcased so effectively in his own Barcarolle – three movements rather than one, unexplained in a note which simply ignored it – there’s little delicacy in the middle ground.

Pure, unorthodox genius: the terms apply both to the three works on the Belcea Quartet’s programme – Haydn at his most compressed, Britten unbuttoned and sunny, Shostakovich hitting the tragic heights – and, if the term “genius” can be applied to re-creative artists, to the players themselves. Corina Belcea could surely have as big a solo career as violinists like Julia Fischer and Lisa Batiashvili, but she chooses to work with equally committed colleagues Axel Schacher, Krzystof Chorzelski and Antoine Lederlin in what is by and large a greater, wider repertoire.

Toby Spence’s recovery from thyroid cancer is a cause for rejoicing, but surely it’s time we focused our attention back on his work rather than his medical condition? Apparently not. The pre-publicity for this Wigmore Hall recital made great play of the “profound insights into the human condition” that the singer acquired during his convalescence – a claim that must have ladled extra pressure onto him as he prepared his programme.

So we glide between seasons from one communicative diva giving her all in a vast space to another casting spells in intimate surroundings. While Joyce DiDonato, not perhaps one of the world’s great voices but certainly a great performer, was captivating the Proms multitudes on Saturday night, the Wigmore Hall’s concert year sidled in with Bryn Terfel and Simon Keenlyside, no low-key singers.

A second visit to hear this already great young Russian pianist in six months was meant for private pleasure only. Yet no-one in the Wigmore Hall audience last night, I’ll hazard a guess, will ever have heard Liszt playing like Sudbin’s in a first half which itself merited a standing ovation, so the world needs to know about it.

Old instruments have found young champions this week in two very different concerts and contexts. In the Wigmore Hall, Mahan Esfahani continued his persuasive rehabilitation of the harpsichord, showcasing not only the expressive range of the instrument itself but – more unusually – its repertoire, in music from Byrd to Ligeti. Meanwhile out in Richmond young singer-songwriter Joseph Reuben took a string quartet on a stylistic journey, blending classical textures and processes with an indie-pop sensibility to create a thoughtful fusion.

If ever there was such a thing as a safe pair of pianistic hands then they would belong to Norway’s Leif Ove Andsnes. There’s a cool, patrician control to everything he does that speaks to thorough preparation, careful interpretative choices and immaculate technique. Thrill-seekers and risk-takers may want to look elsewhere, but for everyone else Andsnes offers the chance to hear cleanly through to the skeleton of a work.

At first it all felt too much. In addition to the garish red arum lilies either side of the platform, an overwhelming scent of eau de Cologne from a neighbour and the always hard-to-fight Wigmore Hall torpor were our diva's pink and purple attire, her flashing jewels, and above all that opulent voice, which even in recitals is more accustomed to bigger spaces and still seemed at times to be channelling her demented Salome from The Rest is Noise festival's opening night.

In our chilled Decembers, even when snowless, winter scenes are visually synonymous with Christmas, and Henry Raeburn’s small painting of The Reverend Robert Walker, from the 1790s, skating with abstracted solemnity and perfect balance on Duddingston Loch, only a few minutes away from the National Gallery of Scotland itself, is one of the most irresistibly memorable seasonal images.

What if Handel, after his death, descended to an eminently civilised afterlife, where he spent his time making music and new friends with the likes of Beethoven and even Jimi Hendrix? That’s the premise of Louis de Bernières’ new play Mr Handel, a show that brings the author himself together with baroque chamber group The Brook Street Band and soprano Nicki Kennedy in a gentle meander through the life and works of baroque’s finest.
