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.

One of the singers smashes out a jittery pulse on a shaman drum and the 50-strong choir intone a chant, while at the front a tenor who looks like a doorman you wouldn’t mess with spits out what sounds like a threat from between gritted teeth. It is the Estonian National Male Voice Choir performing Veljo Tormis’s Raua needmine (“Curse Upon Iron”) and it is utterly entrancing, invigorating – and just a little bit scary.

From the outset, it was clear that this would be a performance of immaculate sonic architecture. Over a soft, deep, and breathy organ pedal the first utterings of the strings sounded tentative, almost improvised, like an artist making the first daubs on a vast empty canvas.

Tenebrae in tenebris: put more plainly, a top choir that’s anything but shadowy, except when it needs to be, doing its bit for the darkness of Maundy Thursday. The thoughtful plaiting of Bach motets with three Tenebrae Responsories and other works by our top choral composer, James MacMillan, worked well until the last work on the programme. Then they had to go and spoil it all by premature ejaculation.

The Facade Ensemble is an interesting chamber group of young players dedicated to exploring 20^th repertoire, in this case John Cage, Arvo Pärt and Gavin Bryars, who celebrates his 80^th birthday this year. The programme, put together by founder and conductor Benedict Collins Rice was contemplative in tone, and an interesting opportunity to hear these experimental and minimal works in a pared-down scoring.
