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.

The Scottish Chamber Orchestra Chorus has a well-established concert life away from the main orchestra; the Royal Scottish National Orchestra Chorus less so. So it was refreshing to get to hear them going it (almost) alone in Edinburgh’s Greyfriars Kirk, and the Bruckner anniversary gave them a good excuse, building their programme around a motet and the E minor Mass.

Antonio Pappano is at a hinge in his illustrious career, as the exciting transfer across London from Covent Garden to the London Symphony Orchestra proceeds, and the word "Emeritus" is added to his title as Music Director of his home-from-home in Rome. A good moment, then, for him to make a statement of commitment to the latter, with a shattering, searing account of probably the most terrifying piece of music ever written: Verdi’s incomparable Messa da Requiem.

That it would be a vividly operatic kind of oratorio performance was never in doubt. Mendelssohn, who said he wanted to create “a real world, such as you find in every chapter of the Old Testament,” instigates high drama with Elijah’s brass-backed opening statement. Pappano then let the orchestral and vocal narrative fly like an arrow, supported to the hilt by all involved, not least four great singers with whom he’d achieved several major successes at the Royal Opera.

Yevhen Stankovych is Ukraine’s most important living composer and – after decades of writing music that seems to grow from this country’s rich black earth, tribulations, literature and folklore – he now contributes, with his latest piece, the most cogent musical event of the current calamity. Psalms of War  premiered last weekend at the Lviv National Opera, is not only the most powerful musical expression of Ukraine’s pain and just war, but probably the most impactful war music of our time.

As any good choral singer knows, you can’t deliver too emphatic a “k” for the opening Kyrie Eleison of any one of thousands of Mass settings. Well, almost. The Scottish Chamber Orchestra Chorus produced such a distinct, detached, and powerful opening consonant for this performance of Bach’s B minor Mass that it seemed to bounce several times round the auditorium before being enveloped by the great tide of chromaticism that characterises this magisterial movement.

If there’s a better name for a vocal group than Roomful of Teeth I have yet to come across it. But if it conjures up images of brash, in-your-face showbiz the reality couldn’t be more different.

The Three Choirs is (are?) off again, for the 295th time, but with a very different look, even from the festivals of my youth, never mind 1715, or whenever the first one was held (there seems to be some doubt about it). 

Sir Mark Elder has a special affection for the music of Elgar. They share a birthday, on 2 June, and his time with the Hallé has included more than one celebration of the composer at this time of year.

Union Jacks could be stowed away, and EU ones figuratively, furtively flourished: this was a concert of celebratory music for a Hanoverian king by a Saxon composer, by then recently become a British citizen, performed by a French ensemble in a Roman Catholic church which once served the Spanish Embassy. The present King, having already made a start repairing Britain’s damaged reputation on the continent by speaking German in Berlin, surely approved.
