High on the hill of fascinating New Ross in County Wexford sits its greatest treasure, the ruined 13th century Gothic beauty of St Mary’s. Unless you come at it from the east, its glories are concealed behind the working church which completes it and takes the place of the old nave, built in 1813 and “improved” twice later that century.

One piece that you’re unlikely to hear at the Lammermuir Festival is Lucia di Lammermoor. As co-director James Waters explained during a drive to the absurdly picturesque church and castle at Crichton (fit setting for a Netflix epic, let alone a blood-soaked bel canto opera), venues and resources do set some limits to works that can be presented to the standards he demands.

In the Saxony of 1725 – still in the grip of Europe’s “Little Ice Age” – Bach and his musicians would seldom have had to deal with the sort of midsummer sauna that enveloped Trafalgar Square last night. Yet, at St Martin-in-the-Fields, Masaaki Suzuki, the Monteverdi Choir and the English Baroque Soloists managed to beat the heat with an exhilarating shirt-sleeved journey through the cantatas that Bach wrote exactly three centuries ago for the Thomaskirche in Leipzig. 

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.

Víkingur Ólafsson had something to prove at the Wigmore Hall. And prove it he did, even if, this time, his Goldberg Variations left a few features of Bach’s inexhaustible keyboard panorama at the edge of his pianistic picture. The much-loved Icelandic chart-topper had promised Beethoven’s final three sonatas for this concert. His last-minute reversion to the familiar Goldbergs – which he played on 88 occasions around the world last season after a supremely successful DG recording – had disappointed a portion of his vast fan-base.

I was in Germany last week, and nearly every town I went to was advertising a St Matthew or a St John Passion taking place in the week up to Easter. It says something about how deeply engrained Bach’s Passion settings are in German culture that they can muster up so many performances while, in most years, we in Scotland get only one for the whole country.

When you’ve already come as close as possible to perfection in the greatest masterpiece, why risk a repeat performance with a difference? Because Bach’s St Matthew Passion needs to be an annual fixture without routine, and because inspirational IBO director Peter Whelan can be guaranteed not only to recapture the magic but to try a few new things, and to choose new soloists with fine judgement.

The musician Abel Selaocoe reaches out to the ancestors, African and European, continuing a journey that spans continents and centuries, an adventurer guided by love and respect for those who have departed, and yet nourish by the splendour of now.

Last night was the first time I had heard the 12 Ensemble, a string group currently Artist-in-Residence at the Wigmore Hall, and I was very impressed, both by the standard of the playing and the enterprising programming. This gave regular audience-members a little of what they’re used to (a chunk of Brahms) and a decent portion of what they’re not.
