The Castalian String Quartet is half what I remember, but only literally: while viola-player Charlotte Bonneton and cellist  Christopher Graves may have departed, their replacements, Ruth Gibson and Steffan Morris, more than earned their laurels in last night’s stunning programme.

I am proud – if surprised – to continue to be pretty much a lone voice in the wilderness singing the praises of the composer Guillaume Connesson (b.1970), whose substantial new string quartet “Les instants retrouvés” was heard at the Wigmore Hall on Saturday.

Ian Page’s “journey of a lifetime” with his Mozartists, taking the greatest genius year by year, lands us in 1773 with the adolescent Mozart's first durable crowdpleaser, the pretty-brilliant motet for soprano and orchestra Exsultate, jubilate (last night was its 250th anniversary). The boy wonder still needs annual support from his elders, though, and as usual we got more than just a sampler of what else was going on musically in that year.

The adrenalin was in full flow yesterday lunchtime at the Wigmore Hall as the dynamic young Mithras Trio delivered a vigorous, toned performance featuring Beethoven, Bridge and an electrifying new work by Joy Lisney. The trio, who have been together for just over five years, are part of Radio 3’s New Generation Artists scheme and dispatched the repertoire with an intensity and expressive range that was often as beguiling as it was exhilarating.

Quite apart from the stunning range of colours and phrasing, Pavel Kolesnikov’s recitals always give you much more than the programme promises. A golden thread through shorter pieces has been one approach, but here he did something different – sailed for the deep waters only in three chameleonic masterpieces, but suggested the connections by unveiling an unnamed work he asked us to listen to in “metaphorical darkness”.

St Mark’s shadow fell gloriously over the Wigmore Hall last night with a programme of Christmas music performed in, or inspired by, the great basilica of Venice. The Dunedin Consort braided festive works from pioneers who wrote for its grandly sonorous spaces – Gabrieli, Monteverdi, Grandi – with pieces by their German visitor and student Heinrich Schütz, culminating with his Christmas Story (1660).

William Thomas has fast made an impact as a rapidly rising (or should that be descending?) star of the bass world. Though he has only recently graduated from the Guildhall School of Music and Drama, his awards include Winner of the Veronica Dunne International Competition and Winner of the Critics’ Circle Award for Young Talent.

There is no mistaking Christian Gerhaher. His voice is a light, agile baritone, and it is utterly distinctive. He is a very verbal singer, and is as happy delivering his lines in a toneless parlando as he is full voice. But when he does increase the colour, a burnished, slightly nasal tone appears, rich but still light. Emotions are always controlled, and the passion will often build gradually but steadily.

A dream pairing of the Freiburg Baroque Orchestra and early-keyboard wizard Kristian Bezuidenhout marked St Cecilia’s Day at the Wigmore Hall with a programme that celebrated music made not in the Black Forest but beside the Thames.

Leif Ove Andsnes has a distinctive voice at the piano; clear, controlled and powerful. He sits upright; his body barely moves, and his head sways gently to the melodies. But he never loses himself in the music, he is always in control.
