At Wigmore Hall the JACK Quartet presented the complete Elliott Carter string quartets in a single day – an astonishing feat given the scale and complexity of the music.

The vocal octet Voces8, approaching its 15^th anniversary, is a purring musical machine: vocally top-notch, precisely and exhaustively rehearsed, imaginative in repertoire and equally at home in Monteverdi and Duke Ellington. And if the classical items grabbed me more than the kitsch swing numbers they ended with, there is no denying the whole concert was put together with panache and musical excellence.

If Gilbert and Sullivan did the Bible it would sound a lot like Hubert Parry’s Judith. Premiered in 1888 and last heard in London a year later, the oratorio – whose principal claim to fame is as the original home of tearjerker hymn tune Repton, better known as “Dear Lord and Father of Mankind – has been lovingly restored to life by conductor William Vann and the English Song Festival, who will record it with Chandos later this year.

We live in a secular age, or so we’re told. Yet we seem to need rituals, the age-old practice and province of religion, as much as ever. It is the achievement of Peter Sellars and Sir Simon Rattle to present one without the other in their concert stagings – "ritualisations" – of the Bach Passions they have taken around Europe and to the US since the St Matthew was first shown this way in Berlin in 2011.

This was a fascinating, unexpected prospect; instantly appealing to anyone who’s ever wondered about the string quartet’s niche in the 21st-century musical ecosystem. Two practically new song cycles for soprano and quartet – Kate Whitley’s Charlotte Mew Songs (2017, but extended earlier this year) and Kate Soper’s Nadja (2015) - framed the Third Quartet (1938) by Elizabeth Maconchy.

Mozart in E flat (the Overture to The Marriage of Figaro) and in G (the K.453 Piano Concerto), and Schubert in C – the “Great” C major Symphony, no less – ushered spring into the Festival Hall on a warm and sunny Sunday afternoon.

No successor has yet been named to Vladimir Jurowski as Principal Conductor of the London Philharmonic, so it is interesting to note that Edward Gardner is making several appearances with the orchestra this season. The two conductors are similar in their dynamic approach and brisk, efficient tempos.

London performances of Alfred Schnittke’s Concerto for Choir are like Meaningful Votes: you wait a long time for one, then they come in clusters. After last night’s Vasari Singers performance, there is only three weeks till the London Concord Singers put this choral monster in front of the voting public again. It remains to be seen if John Bercow steps in to prevent even more.

William Christie kicked off Passion season in London this year with a particularly sombre reading of the St John. The veteran conductor brought his French choir and orchestra, Les Arts Florissants, and a line-up of relatively young soloists to the Barbican.

Standing next to the warm brown beast of a piano built by Blüthner in Leipzig in 1867, Sir András Schiff advised his audience last night to clear their minds and ears of preconceptions. He told us that his rendering of Brahms’s first piano concerto – tonight, he will return to play the second – “should be like a first performance”. In reality, he added, that premiere (in 1859) turned out to be “a colossal failure”.
