Who was a greater composer of words: Schubert or Purcell? A toss-up, I think, after a revelatory concert at the Wigmore Hall by Les Talens Lyriques with the French soprano Sandrine Piau on Saturday. The sheer quality of the poetry Purcell set in his Harmonia Sacra, collections of “divine hymns and dialogues”, is both profound and emotionally direct: “Lord, what is man?”, “In the black, dismal dungeon of despair”, “Music, for a while”...

Not much snow left on the Barbican after last night's barnstormer from Riccardo Chailly and the Leipzig Gewandhaus. What hadn't melted in the flames of the Russian pyre that is Tchaikovsky's Francesca da Rimini would had been swept aside by the great quakes of Respighi's tub-thumping Pines of Rome. And the icy refuseniks clinging to Barbican pavements? Note-gobbling piano virtuoso Arcadi Volodos - doing a very good impression of a snow shovel in Tchaikovsky's First Piano Concerto - was dealing with that.

Despite footsteps in the snow, as creepily characterised by Debussy's prelude of the same name, and sleighbells to launch a childlike symphonic journey, interior illumination should have been at the core of this concert. Sadly, given Colin Matthews's refined but fussy designer lighting in his Debussy orchestrations, a low-wattage Rimbaud/Britten zoo from one-tone soprano Christine Schäfer and hard sunbeams failing to probe the inner mysteries of the tomb-effigies Mahler envisaged in his Fourth Symphony's slow movement, it wasn't. Fortunately Vladimir Jurowski found novelty enough elsewhere to keep us from slumping in the semi-dark.

Visits from the pick of Europe’s Baroque orchestras – Concerto Köln, Europa Galante, Le Concert d’Astree, Les Musiciens du Louvre – are a blissfully frequent occurrence in London, an alternative and supplement to our own ever-growing roster of period talent. A tour by a North American ensemble is, by contrast, something of a rarity, and I can’t have been alone last night in hearing the much-lauded Apollo's Fire (otherwise known as the Cleveland Baroque Orchestra) live for the first time. “Hearing”, however, rather fails to encompass the visually charged, minutely stage-managed musical theatrics on display from Jeannette Sorrell and her irrepressible team of musicians.

An entire evening of Schumann for two would usually cue singer and piano. Not that the majority of Lieder specialists, blessed as naughty Anna Russell once saw it "with tremendous artistry but no voice", could hold the spell for that long. Julia Fischer is one of the half-dozen violinists in the world with the greatest artistry, a golden "voice" and a habit of choosing partners like Martin Helmchen, very much on her level. The only trouble is that Schumann songs can capture a world in 90 minutes, while the three lateish sonatas run a more limited if quirky gamut.

Perhaps I’m being too literal-minded, but demanding South American music from a concert programme advertised as “South American Baroque” doesn’t seem entirely unreasonable. When you add Colombian-born soprano Juanita Lascarro as soloist and Brazilian Rodolfo Richter as leader it seems actively desirable – a chance to encounter an underexposed seam of music in the hands of expert guides. Turns out that all musical roads lead back to Europe, to the ubiquitous Scarlattis, Handel and Hasse, and despite a few exotic excursions to the New World it was in the familiar Old that we spent the bulk of our evening.
