Ten days ago I reviewed the First Night of the 2017 Proms. Last night I was back at the Royal Albert Hall to hear the First Night of the 1966 Proms. This time-capsule experience was courtesy of a re-enactment of Sir Malcolm Sargent’s 500^th Prom, in what turned out to be his final season. It gave an idea of Sargent’s musical tastes – middle-of-the-road classics and English music – and, in places, of his famously audience-pleasing conducting style.

It’s at times like this that I give thanks for the Proms. Who else would (or could) have put together a programme pairing Berlioz’s Symphonie Fantastique with an 18th-century sonic fantasy, or topped it off with a substantial UK premiere? A bit bonkers on the page, it remained so in performance.

The ideal First Night of the Proms sets the tone for the season, perhaps flagging up some of the themes to be followed up later, offering a blend of novelty and familiarity, and preferably ending with a roof-raising choral blockbuster. This programme successfully ticked those boxes, but took until the second half to really catch light.

It may not have had the symbolism of the Ariana Grande concert just down the road, but in its own way the joint Hallé/BBC Philharmonic performance of Schoenberg’s Gurrelieder said as much about Manchester as the rock jamboree did.

Made from girders, say the brewers of an infamous Scottish fizzy drink. If you could siphon the music of Edgard Varèse into a can, that’s what it would taste like. Blunt, acrid, inimitable, fizzing with closely guarded, possibly unpleasant ingredients. The danger was that exposure to his entire output in one day would prove no more palatable than chugging through a two-litre bottle of Irn-Bru.

Bomb-dropping is the new black again in Trump's dysfunctional America. Awareness of that contributed to the crackling cloud of dynamic dread hanging over last night's concert staging of John Adams's opera-oratorio - my description, not his - about the July 1945 desert testing of the plutonium bomb under the supervision of self-divided Robert Oppenheimer, an American Faust.

Not your usual blockbuster for Holy Week, this. In other words, neither of the Bach Passions but a Requiem, and not – these days, at any rate – one of the more often-performed ones (it's not among the 79 works listed in The BBC Proms Guide to Great Choral Works).

A new opera from Peter Eötvös is a major event. More than any other composer today, he has the ability to create sophisticated contemporary music that supports and enriches sung drama.

It's official: if you want to be guaranteed an infallible musical adrenalin boost in London, you can always be sure to find it with Finnish conductor Sakari Oramo and his BBC Symphony Orchestra. And it's not just a question of splashy excitement: Oramo is a rigorous rehearser. Detlev Glanert's fiendish new tone poem Megaris would not have been half as vivid or pleasurable without extraordinary preparation.

The BBC Symphony Orchestra has continued its long-standing support of British contemporary music with this première of a new commission, Michael Zev Gordon’s Violin Concerto for violinist Carolin Widmann.
