It’s nobody’s fault, but – try as they might – the BBC Proms can often feel rather middle-aged. Whether it’s the lumbering albatross of a building, the ushers in their dated, casino waistcoats or the tone of zealous jollity (Have fun! But silently and according to the rules!), it somehow all adds up to a lack of freshness, spontaneity. Thank goodness for Aurora Orchestra.

In this most atypical Proms season this was actually an archetypal Proms programme: a world premiere: a neglected masterpiece and a good solid 19^th-century symphony for those put off a bit by the first two. But this American-themed programme never felt run of the mill. There was a palpable energy in the hall, for both audience and orchestra, to be in the same space again.

In a normal year, the National Youth Orchestra of Great Britain descends mob-handed on the Royal Albert Hall for a Prom that complements the sheer quality of the young musicians’ work with joyful, raucous, roof-raising quantity. I recall a Turangalîla symphony in the other Olympic season of 2012 that rocked all Kensington with its heaven-storming, gold-medal exuberance. This summer, with caution still the proper watchword, the NYO has built its admirable “Hope Exchange” programme into a series of steps into the musical future.

Nominally, this was a programme of three symphonies. The first, though, sounded like music re-cut and pasted from a very British film and the second was a suite, albeit impressively reworked, from an opera.

Two nights after the Scottish Chamber Orchestra had brought the first great E flat major symphony to the Proms – Mozart’s 39th – a serendipitous change of programme on Tuesday gave us the second: Haydn’s “Drumroll”. An equally serendipitous change of conductor saw Ben Gernon get the evening off to a deceptively simple start: no fancy-dan cadenza from the BBC Philharmonic’s timpanist, just enough of a flourish to get everyone’s attention as Haydn probably had in mind.

The Proms are back, even if they don’t yet feel remotely normal. With audiences timid about mass events, and about a third of the arena roped off to protect a TV camera mounted on something vaguely resembling a diplodocus, yesterday’s seemed less of a Prom than – well, a decent concert on a wet Monday night.

Did absence from Albert’s colosseum from early September 2019 until now and a roof-raising finale hoodwink many of us into thinking Dalia Stasevska’s interpretation of Sibelius’s Second Symphony among the greats? Having listened to it again on the BBC Radio 3 iPlayer this morning, I'm convinced not; this was the real deal.

The Aurora Orchestra’s trademark expertise in playing symphonies from memory arguably reached new heights this week as they tackled Beethoven’s Seventh, first in performances with a live audience and then, yesterday, in an empty Royal Albert Hall for what’s left of the Proms. 

“Did you bring any Bach?” was not a question to ask of Jonathan Scott before he launched into his jaw-dropping Prom on the Royal Albert Hall's 1871 Henry Willis organ – the largest in the world at the time. augmented in its 2002-4 overhaul to 9,999 pipes. What Stokowski did for the Toccata and Fugue in D minor Moore achieved, in reverse as it were, for four orchestral classics in a feat of stamina live on Saturday evening.
