It’s Christmas already at Wigmore Hall. Or advent at least – this concert of Bach Advent cantatas was presented by the English Concert without apology or qualification, despite it still being the middle of November. But it proved a welcome fillip for a wet and dreary November evening, with the energetic and engaged playing of the small ensemble bringing out all the life and playfulness in Bach’s scores.

Presenting the last Mozart symphonies as a three-act opera for orchestra, as Richard Tognetti and his febrile fellow Australians did on Monday, was always going to be a supreme challenge. It worked, as Boyd Tonkin reported here. Since then, the Barbican's grandiosely-named "International Associate Ensemble" has opened up the repertoire, synchronising with film (on Tuesday) and ending its mini-residency with the kind of vibrant rattlebag for which it's rightly celebrated.

Bach specialists like to explain that the second book of preludes and fugues in The Well-Tempered Clavier, composed around 1740 and thus almost two decades after the first, draws on more of the fancy and daring “modern” music of its time than its more traditional predecessor. Yes, but there’s modern and there’s modern. I don’t think the scholars have yet argued that, among the ear-stretching range of moods and effects encompassed across these 24 pieces, comes a spooky anticipation of Seattle grunge.

First it was the soft acoustic guitar playing, which on three occasions to three very different audiences won a silence so intense it was almost deafening. Then the loud electric, first heard in Anstruther's Dreel Halls as part of the 2017 East Neuk Festival; the ear-plugs we were given at the door proved unnecessary – just – but the shock of Julia Wolfe's LAD, transferred from nine bagpipes to Sean Shibe live alongside eight recorded selves, was massive.

Brits are the folk you expect to encounter the most in the rural-England-on-steroids of the beautiful Dordogne. In my experience they outnumber the French, at least in high summer, not just as visitors and retired homeowners but also as artisans selling their wares in Riberac's big Friday market.

A complex Swedish product to unpack, this one. Someone in the BBC must have worked out that it could do with a detailed instruction manual to help people with the task: the programme booklet duly ran to a full 50 pages.

Let's be honest, this is the least interesting Proms season on paper for years, at least in terms of adventurous repertoire choices, following on the heels of the best in 2017. Yet in statistical terms it's more comprehensive and multi-media-friendly than ever, starting tonight with a free "Curtain Raiser" performance before the official First Night tomorrow - see David Kettle's choice below – and ending some 75 main Proms and 11 smaller-scale beauties later on 8 September.

There is a tide in the best-planned festivals that comes in and out almost imperceptibly, bringing with it changes as the days move on. Put it down to the kind of perfect planning that discards any one rigid theme, and to forging long-term links with performers who don't just pop in for one concert.
