In a programme note for the St John Passion at the Barbican, the Academy of Ancient Music’s chief executive called their Easter performances of Bach’s compressed gospel tragedy a “ritual”. You understand why that word claims its place. However, there’s not much consciously liturgical about the AAM’s musical approach.

If not quite his last will and testament, the work now known as Bach’s Mass in B Minor represents a definitive show-reel or sample-book of the Leipzig cantor’s choral and orchestral art. Its complex patchwork of manuscripts dating from different decades only came together for a full public performance in 1859: the year in which Wagner completed Tristan und Isolde. 

I don’t really want to talk about this year. Genuinely.

It’s been so horrific on the macro scale with deranged Fascism and the effects of rampant and undeniable climate change looming everywhere you look – and on the personal level I’ve been been bombarded with all the inevitable, arbitrary slings and arrows that life can muster, from multiple bereavements on down – that I’d very much rather just neck a load of tranquilisers and fine wines and resolutely enter my hands-over-ears, “lalalala can’t hear you”, era.  

For 30 years, La Serenissima have re-mapped the landscape of the Italian Baroque repertoire so that its towering figures, notably Vivaldi, no longer look like isolated peaks but integrated parts of a spectacular range. The ensemble founded by violinist Adrian Chandler delves deep into the archives to recover neglected music not just as a nerdish passion (though there’s nowt wrong with that) but the basis for practical performing editions that restore these lost sounds to life.

Waiting, and hoping, may prove just as intense an experience as the fulfilment of a wish – or of a fear. Bach knew that, and infused his Easter Week music with a sense of suspense and anticipation built into vocal and instrumental lines that build and strive and stretch towards a climactic revelation that, until the very end, remains just out of reach. 

It’s hard to imagine that any London audience this winter will hear more thoroughly gorgeous singing – or more refined musical artistry all round – than Nardus Williams delivered at the Wigmore Hall on Sunday afternoon. This was a magical hour of early-Baroque Italian bliss.

“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.

It never rains but it pours – and hails, snows or, above all, thunders. The presiding tone of Semele, in Adele Thomas’s new production for Glyndebourne, matches the current English summer with its grey skies, glowering clouds and stormy outbursts. Jove’s evidently in a rage, despite his rejuvenating lust for the Theban king’s daughter, Semele. He’s not the only one: the first of many lightning-bolts – designed by Peter Mumford with Rick Fisher – that flash around Annemarie Woods’s crepusular set illuminate lonely Juno, spurned and seething spouse of the heavenly overlord.

Cotswold Line railway stations currently sport posters for Alex James’s “Big Feastival”, in which the ex-Blur bassist hosts a food-and-music jamboree on his cheese-making farm. Just up the road at Longborough Festival Opera, the crowd gathered on stage for the nuptials of Orfeo and Euridice would fit snugly in chez James as well.

Escapees from Eurovision in Westminster on Saturday night might have discovered that a continent-wide enthusiasm for crowd-pleasing international styles arose long before the age of glitzy pop. Two accomplished Spanish groups performed at St John’s Smith Square within this year’s London Festival of Baroque Music. Both came with an attractive, unfamiliar 18th-century repertoire from their homeland. It showed that, across the decades from Handel to Haydn, the hegemonic sounds of Italy could be zestfully customised to suit national tastes.
