Thomas Adès and the Britten Sinfonia are embarking on a three-year project, coupling the symphonies of Beethoven with works by contemporary Irish composer Gerald Barry. Adès is keen to highlight the radical vision of the two composers, so expect stark juxtapositions and uncompromising readings. The project began on a more modest scale, however, with this recital of chamber works, given excellent performances and full of intriguing surprises.

Bernard Haitink is one of the great Bruckner conductors of our time. His interpretations are expansive yet vivid and always go straight to the heart of the music. But he is also an old man, and physical frailty is increasingly inhibiting his work, reducing the spontaneity of his communication with the orchestra. The results are both frustrating and inspiring, with details lost and clarity of texture often compromised.

This was a very fine concert indeed, plus a lot more. The first half was a very carefully planned series of unveilings around the theme of Béla Bartók and Hungarian folk music, the second an overwhelming performance of his Duke Bluebeard’s Castle.

It could have been your standard Russian touring programme: Tchaikovsky ballet music as hors d'oeuvre, Rachmaninov piano concerto, Shostakovich symphony. But the symphony was hardly the usual (Sixth rather than Fifth or Tenth).

On paper this was a knockout concert: Gramophone Award-winning Belgian ensemble Vox Luminis teaming up with the wonderfully gutsy Freiburg Baroque Consort to perform Monteverdi’s Vespers in the composer’s 450^th anniversary year – one of the highlights of this year’s London Festival of Baroque Music.

Enlightenment is a wonderful idea, and the members of the Orchestra of the Age of Enlightenment who played Bach’s six Brandenburg Concertos in Manchester’s Bridgewater Hall last night brought the wisdom of today’s period instrument movement to bear on music that most would see as belonging to the age of the pre-Enlightenment. Present-day enlightenment lies not just in historical accuracy, however, but also – from an audience point of view – in catching the spirit of its original creators.

It’s been said – and with some justification – that John Wilson’s own Orchestra has the finest-sounding string section in the world today. What’s certain is that when Wilson guests with other orchestras, he transforms their string sound. It’s not merely the unselfconscious touches of period style – those perfectly gauged expressive slides – and nor is it just the unforced luminosity: how the surface sheen seems to be lit from within.

Few young singers make a UK recital debut like Lise Davidsen’s. But then, few singers come to that debut with such a weight of reputation and expectation. Taking not only the First Prize but also the Audience Prize and Birgit Nilsson Awards at 2015’s Operalia competition, established the then 28-year-old Norwegian soprano as one to watch.

Has Glasgow’s Tectonics weekend turned away from its wilder excess? Has it, in its fifth outing, even – well, grown up and got serious?

Made from girders, say the brewers of an infamous Scottish fizzy drink. If you could siphon the music of Edgard Varèse into a can, that’s what it would taste like. Blunt, acrid, inimitable, fizzing with closely guarded, possibly unpleasant ingredients. The danger was that exposure to his entire output in one day would prove no more palatable than chugging through a two-litre bottle of Irn-Bru.
