While the Proms were ringing out the old season, the Wigmore Hall ushered in the big celebration of 2020: the 250^th anniversary of Ludwig van Beethoven’s birth. The venue’s year-long festival (actually longer – the actual birthday is December ‘20) kicked off with a Beethoven weekend with more than just Beethoven in it.

Any festival would be proud and honoured to end with the great Elisabeth Leonskaja playing the last three Beethoven piano sonatas. Here the Everest was swiftly scaled as the tenth concert of a packed Wigmore Hall weekend.

Simon Rattle has a knack for unearthing large-scale orchestral works that pack a punch. Olivier Messiaen’s Éclairs sur l’Au-Delà … (Illuminations of the Beyond …) was completed in 1991, a year before the composer’s death, and is both a reflection on mortality and a summation of his life’s work.

The BBC put social and ethnic diversity at the heart of this Last Night programme. The concert opened with a new work, by Daniel Kidane, called Woke, and the first half was dominated by the music of black and female composers.

For a few seconds last night, the Royal Albert Hall turned into London’s biggest – and cheesiest – disco. At the end of the Ball movement in the Aurora Orchestra’s dramatised version of the Symphonie Fantastique, Berlioz’s tipsily lurching waltz climaxed in a lightshow that sent a galaxy of glitterball stars swirling through the auditorium.

Blame it on the box set. The four Bach Orchestral Suites fit neatly together as a recording project. They used to fill out the four sides of a double LP back in the early stages of the baroque revival. Completists and collectors could rejoice then, and with many more versions to choose from, they still can now.

Semyon Bychkov was a surprising choice to take over the Czech Philharmonic last year, a conductor with few obvious connections to Czech music. But on the strength of this visit to the Proms, they make a good team. Bychkov communicates fluently with the players, conveying power and passion, and detail too, but without any overt theatrics at the podium.

Known as "Heldenmommy" to her fans on Twitter, Christine Goerke is a Wagner soprano of and for our time. You won’t find her recordings on the major-label behemoths but her reputation is built on two decades of producing the goods night after night at opera houses across the US, notably the Metropolitan in New York. On the other side of the Atlantic, her Brünnhilde has filled the Usher Hall through the course of a four-year Ring cycle at the Edinburgh Festival.

This is the kind of thing that the Proms does well – indeed, where else would it get an outing? A "big event" piece of massive scale in terms of size and duration, in many ways a modern Spem in Alium, but where Tallis’s 1570 piece demands 40 singers, In the Name of the Earth ups the ante to 700-plus voices, led by eight conductors and arrayed around the Royal Albert Hall.

Weirdly enough, it was “Tea for Two” that definitively proved her class for me. As a second encore to Rachmaninov’s Third Piano Concerto, after a mesmeric transcription of that composer’s Vocalise, Yuja Wang’s goodbye treat channelled the mighty Art Tatum with a scrupulous respect for the jazz master’s timing and phrasing.
