What better way to start a season about the Earth than by looking back on it from an astronaut’s perspective? At a time when the activities of assorted billionaires and emerging superpowers are making the space race topical again, it feels more than appropriate for Kings Place to begin its Earth Unwrapped programme with Terry Riley’s Sun Rings.

Gustavo Dudamel and the Simón Bolívar Symphony Orchestra of Venezuela took the Barbican by storm last night with a thrilling account of Mahler’s Third Symphony, his great exploration of the cosmic order, ascending from raw paganism to sublime transcendence. It's technically the longest symphony ever composed, and here it swept the audience through an epic journey that tilted between passages of gossamer-like intimacy and outbursts of apocalyptic rage.

This concert was an effusion of pure joy. Billed as the German National Orchestra, the Bundesjugendorchester (Federal Youth Orchestra), all of whose players are aged from 14 to 19, make a glorious, powerful sound. Just over 100 teenage musicians packed the extended stage at Cadogan Hall last night, and played to a nearly full house.

Forthright and upright, powerful and lucid, the frank and bold pianism of Leif Ove Andsnes took his Wigmore Hall audience from Norway to Poland (or rather, Paris and Majorca) with a final stop in France. A recital that began with two large-scale Norwegian sonatas – one a remarkable discovery – culminated in the ostensibly remote sound-world of Chopin’s 24 Preludes, part-written on the Balearic island.

Top Brownie points for the BBC Philharmonic for being one of the first (maybe the first?) to celebrate the birth centenary of Pierre Boulez this year. His Rituel – in memoriam Bruno Maderna was paired somewhat uneasily with a second half of bonbons by Ravel (it’s his 150^th anniversary year, too).

Mark Wigglesworth was the maestro who piloted both parts of the programme, however, showing equally calm assurance and sympathy with their differing idioms.

There’s nothing like an anodyne new(ish) work to give a masterpiece an even higher profile. Rachel Portman‘s Tipping Points, promising to address climate change issues, was so bland and featureless it could have been composed by AI. Any one bar of Shostakovich’s Tenth Symphony, on the other hand, shows originality of throught within a tradition, and unlike the Portman near-vacuum it challenged the musicians of the National Youth Orchestra of Ireland to the limits.

In one sense it was a New Year’s Day “nearly”, just stopping short of giving us the already great Irish lyric-dramatic soprano Jennifer Davis in the music of the man she was born to sing, Richard Strauss. Berlin will witness her Arabella shortly, but the one Bavarian intruder in the otherwise all-Viennese carnival yesterday afternoon, the Moonlight Music from Capriccio, stopped before the Countess’s final scene.

As always, great concerts have outnumbered great opera productions over a year, and all of our national orchestras can be proud of their record. I’ve sometimes started by celebrating youth, and it’s good to be able to do that in the shape of two competition finales totally satisfying as programmes. The palm, though, goes to two veterans who made me wonder at their ease and natural communication.

“O stay and hear,” sings Twelfth Night’s jester Feste in his song “O mistress mine”, “your true love’s coming,/ That can sing both high and low.” And loud and soft, earthbound and airborne, Heldentenor-grave and night-club frivolous: Nicky Spence’s wide vocal span and stylistic versatility made him the ideal soloist for this cheerful post-Christmas canter through several centuries of Shakespeare songs.

Enough is as good as a feast, they say. But sometimes, especially at Christmas, you crave a properly groaning table. At the Wigmore Hall, The English Concert, directed by Harry Bicket, concluded their festive Baroque banquet with Bach’s Magnificat – complete with its four Christmas-tide interpolations. They had prefaced the Bach with a trio of lesser-known seasonal pieces dating from the preceding decades, by Charpentier, Stradella, and Purcell. That might sound like a light plate of rather scholarly, even austere, hors d’oeuvres.
