Because he dramatised power, Shakespeare never really goes out of fashion. Treatments of his plays do though, and the RSC’s Measure for Measure, a transfer from Stratford set in turn-of-the-century Vienna, feels distinctly slack. The backdrop is supposedly a city filled with refugees, artists, political movers and shakers and members of the upper-class and demimonde.

For better or worse, because of Visconti’s classic film the Adagietto of Mahler’s Fifth Symphony now inevitably means Venice in its gloomiest moods. So there turned out to be a grim timeliness in a performance on an evening that coincided with the most devastating “acqua alta” to flood the city in half a century. Yet, in keeping with everything he does with the London Philharmonia Orchestra, Vladimir Jurowski’s reading at the Royal Festival Hall made us think afresh about an iconic work and dispel its more hackneyed, reach-me-down associations.

There are now two septuagenarians playing Schubert at a level no other living pianist can touch.

Charismatic, full of vital elan to the end, inconsistent, fitfully creative, a casually anti-semitic Conservative Catholic married to two of the greatest Jewish artists, Alma Mahler/Gropius/Werfel née Schindler can never be subject to a boring biography. A child of her fin de siècle time, torn between the need to be free and the will to inspire great figures, she was all too often gauged by the men who loved and tried to dominate her.

I last saw this Magic Flute, directed by Dominic Cooke, when it was new, some 14 years ago, and I remember it mainly, I’m afraid, for its lack of visual charm.

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.

You can always be sure of impeccable casting and spirited playing as Ian Page takes his Classical Opera through Mozart year by year. Just don't expect more than the glimmer of genius to come in 1768, though. It doesn't matter in those admirable showcase programmes highlighting the young Amadeus alongside more mature voices of the year in question.

If Hugo von Hofmannsthal's libretto for Richard Strauss in their joint "comedy for music" is the apogee of elaborately referenced dialogue and stage directions in opera, Richard Jones's realisation - for all that it throws out much of the original rulebook - may well be the most rigorously detailed production on the operatic stage today.

Let's face it, Robert "Cabinet of Dr Caligari" Wiene's 1926 film loosely based on Strauss and Hofmannsthal's 1911 "comedy for music" is a mostly inartistic ramble. Historically, though, it proves fascinating.

Living-museum recitals on a variety of historic instruments pose logistical problems. Telling The Arts Desk about his award-nominated CD of mostly 19th-century works for horns and pianos, Alec Frank-Gemmill remarked on the near-impossibility of reproducing the experiment in the concert-hall: playing on four period horns would need several intervals, and colleague Alasdair Beatson would hardly be likely to have the four pianos in the same room.
