Back in 1990, John Eliot Gardiner with his Monteverdi Choir, English Baroque Soloists and world-class singers set the South Bank alight with revelatory concert performances of Mozart’s Idomeneo and La clemenza di Tito. Now he's done it again for an even quirkier masterpiece, burning away any Albert Hall mists with the best possible voices and an “Orchestre” which can be called “Révolutionnaire” but decidedly not “Romantique” when it comes to the Missa Solemnis.

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.

By my count, tomorrow’s Proms première of Marius Neset’s jazz epic Geyser will be my 51st performance conducting the London Sinfonietta. It’s a tally that has crept up over the last decade, and is something I could hardly have dreamed of more than twenty years ago when I started to make regular trips into London to see Oliver Knussen conduct Sinfonietta concerts at the Queen Elizabeth Hall. 

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.

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.

Long goodbyes don’t get grander, warmer or more passionate than this. Sir Simon Rattle began his farewell season with the London Symphony Orchestra with a Proms performance of Mahler’s Second, “Resurrection” Symphony – the mighty work that has waymarked the major moves of his career.

Like many people, I grew up with cut-and-paste Handel. It could take decades before you found out where that shiny snippet of a childhood earworm truly belonged.
