So the bubble of reactionary brouhaha over the Last Night of the Proms quickly burst: there can be no argument about singing “Land of Hope and Glory” or “Rule, Britannia!” when they’re to be presented in their original Proms forms (Elgar’s Pomp and Circumstance March No.

As two weeks of livestreamed Proms begin tonight, we just want to be there in the Royal Albert Hall. The exuberance of our lead picture tells one story of a Prom which had to be witnessed live to be believed: the annual visit of the National Youth Orchestra of Great Britain last year, with brilliant Auerbach and Prokofiev under Mark Wigglesworth, and much-loved Nicola Benedetti uniting with them in Tchaikovsky's Violin Concerto.

What a difference a year makes. Live Proms will be back from Friday, but the very essence of the world's biggest music festival will be missing: the audience, and especially the Prommers whose rapt attention while standing has taken so many visiting orchestras by surprise. No doubt the rapport between conductor and players will be electric at times, but the third point of what Britten called the "magic triangle" of composer, performers and audience will be notable by its absence.

It seems a shame that large-scale organisations can’t be more flexible when government guidelines shift. True, the arts couldn’t jump at two days’ notice when outdoor events were licensed by our ever-vacillating government. The BBC Proms could have adjusted, but it seems the programme is now carved in stone – mostly archive material until the end of August.

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.

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.
