The annual St Matthew Passion from the Dunedin Consort is one the most reliably beautiful jewels in Edinburgh’s musical year. They do the St John Passion much less frequently; in fact, this is the first time I’ve heard them do it, maybe motivated by its tercentenary this year.

At the start of his 75-minute pre-concert lecture on Sunday, the incomparable András Schiff staked quite a claim for the piece he was about to perform: Bach’s The Art of Fugue was, he said: “the greatest work by the greatest composer who ever lived”.

And a wise one: this concert was only the second time he would ever play it, the first having been in Berlin last January. Because, he said: “I’ve waited 70 years to play this work… You cannot climb Mount Everest immediately… this is the climax.”

After last year’s small-scale, big-impact Messiah in the Wigmore Hall, superlatives are again in order for the IBO’s performance of the greatest musical offering known to humankind. With the fluency established by that most supple of directors Peter Whelan at the start of Bach's opening chorus leading to the astonishing heft of nine singers and gleaming instrumentalists at its culmination, we knew we were in for something approaching perfection.

Prior to their Messiah, due this evening, Stephen Layton’s choir Polyphony brought a version of Bach’s Christmas Oratorio to the seasonal festival at St John’s Smith Square. You can of course slice and serve Bach’s majestic 1730s combination of musical leftovers (both sacred and secular) and fresh dishes in a variety of ways. But Layton’s choice spun a special mood of its own.

We think of the Wigmore Hall as a venue for intimate revelations, but in the right hands it can feel like a stadium. Last night’s all-Bach programme of festive music from the London Handel Players managed to embrace both moods.

“Nobody likes a Messiah…”, deadpanned Robert Hollingworth, with the timing of a practised stand-up. After a pause, “…more than I do.” At St Martin-in-the-Fields on Friday evening, however, the seasonal blockbuster did not, just for once, feature on the festive menu. Instead, Hollingworth’s ever-enterprising ensemble I Fagiolini served up a savoury and well-spiced alternative to Handel’s ubiquitous staple.

There’s a game called Whamageddon, where people see how deep into December they can go without hearing “Last Christmas”. I’m like that, but with the Bach Christmas Oratorio, and this year I made it four days. And who would want to wait any longer? Last night I was at the Voces8 Centre in London as part of a live audience for a concert also streamed in the ongoing Live from London series, started during the Covid summer of 2020 and continuing to flourish.

The showman was back – and, bless him, he can still sell every seat in a big hall even if the programme offers close on an hour and a half of unalloyed Bach.
