This was at first sight a somewhat ordinary looking programme for the BBC Philharmonic: Beethoven, Brahms … even Stravinsky doesn’t frighten a Saturday night audience in Manchester these days. 

In a Renaissance artist’s studio, a wannabe master proved his skill by drawing a perfect circle. Perhaps playing Beethoven’s A minor Bagatelle (aka “Für Elise”) as an encore should count as the pianist’s equivalent. At the Barbican last night, Alice Sara Ott did just that with the ubiquitous ring-tone earworm.

The Concertgebouw Orchestra of Amsterdam began their two-concert visit to the Barbican with a crowd-pleasing programme: Brahms and Beethoven. We are used to hearing the pinpoint precision and transparent textures of the London Symphony Orchestra from the Barbican stage, but the Concertgebouw has a different sound.

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.

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.

Sibelius or Nielsen symphonies? Last night, with the Finn’s Seventh in the first half and the Dane’s “Inextinguishable” (No. 4) in the second, choice should have been impossible. Francesco Piemontesi or Jan Lisiecki? I’d have been equally happy with either pianist, but there we had no option: PIemontesi was unwell and the Canadian took over. The Beethoven Fourth Piano Concerto we heard as a result was fresh and electifying.

Isabelle Faust and Alexander Melnikov concluded their three-concert survey of Beethoven’s violin sonatas on the warmest day of the year. But the Wigmore Hall is always comfortable, and the temperature was well under control. The heat deterred the audience, but those who did attend made up with their impressive enthusiasm, unusual even for the ever-engaged Wigmore regulars.

Considering its status as the most famous piece of classical music [citation needed], Beethoven’s Fifth Symphony is actually quite rarely programmed in London. I can’t remember the last time I heard it live before last night, and it took the visiting Concerto Budapest Symphony Orchestra to return it to the repertoire. They played this often stern music with a smile on their faces, as they did the accompanying Mozart and Bartók.

Dresden is filled with music at this time of year. The Dresden Music Festival runs through May and early June, with concerts at all the famous venues – the Frauenkirche, the Semperoper – but also recitals in smaller halls and unlikely settings.
