In more ways than one, Beethoven’s last piano sonatas can make the listener lose track of time. It’s not just the delirious freedom with rhythm, accents, signatures and note-values that the ageing, afflicted composer of Op. 109, 110 and 111 unleashes in these epoch-shifting works. Played with as much consummate, fuss-free art as Sir András Schiff brings to them, the unfolding drama of this revolutionary trio can truly seem to stop the clock.

Match the most multi-timbred, flexible orchestra in the world with the iridescent peak of symphonic mastery, and you have an assured winner of a Prom. Yet not even Kirill Petrenko’s previous London performance of Mahler’s Seventh with the Bavarian State Orchestra, nor the brilliance of his two previous Proms with the Berlin Philharmonic, had prepared me for the miracle he achieved last night with players who will clearly do anything for him.

Last night’s riveting, meticulous account of Beethoven’s Nin^th from the Chineke! Orchestra was as daring in its restraint as it was thrillingly revelatory. Right from the subtle shimmer of the first movement’s opening cascades it was clear that this interpretation had put each bar under the microscope and found it teeming with new life.

When I worked in the Music Discount Centre decades ago, and non-stop CDs in the background were ordained, a customer remarked wryly of eight Bayreuth Festival horns playing Wagner “very crepuscular”. Five cellists playing Bach and Villa-Lobos as darkness fell beneath the roof of Peckham’s Multi-Storey Car Park could also be so described, but as a compliment: this was a grave and beautiful way to start the perfect entertainment.

Asked which work suits capricious Albert Hall acoustics best, I’d say Elgar’s The Dream of Gerontius, partly due to the choral billows – this year there’s been an extra thrill about massed choirs – but also because the Kensington colosseum haloes this spiritual journey of a soul. Best singer in the space? Based on years of Proms experience, surely the palm should go to tenor Allan Clayton, ringing of tone and so clear in diction that you can hear every word.

A strong team of musical chefs can blend and spice Bach’s mighty Mass in B Minor in a variety of different ways, and still prepare a feast to savour. We don’t know exactly why Bach felt compelled to bundle his decades of genius into this late portmanteau showcase, only that he did – and that its credible interpretations can span contrasting views.

The Voces8 Live from London, now in its seventh iteration, has progressed from streaming choral chamber music from an empty studio to an 80-strong visiting choir in a packed Christ Church, Spitalfields. In doing this the festival has retained its best features – a variety of repertoire, collaboration with a range of ensembles – while adding scale and the warmth of a live audience.

For the penultimate concert in the Philadelphia Orchestra’s residency at the Edinburgh Festival, the chosen repertoire was evidently considered so obscure that the box office managers didn’t even try to sell any tickets in the Usher Hall’s cavernous upper circle. To shut off nearly half the concert hall for a world class orchestra that has crossed the Atlantic shows either a healthy disregard for the fickleness of audience taste, or a near suicidal disinterest in box office revenue.

Schoolteachers know – even if only the very best can put it into practice – that faced with a noisy classroom you shouldn’t raise your voice, but rather speak quietly. Over recent Proms seasons audience coughing has reached extreme levels, so the charismatic Finnish violinist Pekka Kuusisto took the bold course in playing Vaughan Williams’s The Lark Ascending as softly as it is possible to do – and the hall responded with the most silent, rapt attention I can remember there.

This is the Pavel Haas Quartet’s second visit to a Scottish festival this summer. They were among the stars of the East Neuk Festival at the start of July, and they were every bit as scorching in this Edinburgh International Festival concert.
