Youth may have vanished from the title, and its first flush is gone from the cheeks of most of the young persons. Now they’re in their prime, a magnificent sight – and the sound, too, is that of a world-class orchestra with a voice. Which we heard at its most distinctive, deep and muscular, from the strings in the opening signals of Beethoven’s Fifth Symphony. So what went wrong with the music from Wagner’s Ring in their first 2015 Southbank concert’s second half?

Even the most reluctant of completists should find the prospect of the Beethoven works for cello and piano undaunting. In their totality, these pieces consist of just five sonatas and three sets of variations, which fit neatly on to just two CDs, or occupy two recital programmes. The works are also very important in the early development of the solo cello repertoire. Beethoven biographer Jan Swafford describes the “confident, ebullient, fresh and youthful” sonatas of Op 5 as a genre which the composer, at the time, had “virtually to himself".

This concert was part of a tour of Canada’s National Arts Centre orchestra to five cities in the UK themed around the anniversary of the start of World War One. The Ottawa-based orchestra joined forces with the Royal Philharmonic Orchestra and the London Philharmonic Choir for this London centrepiece to the tour, under the baton of violinist-turned-conductor Pinchas Zukerman.

Musical theatre needn’t be dominated by the human voice. Instrumental dramas with an element of acting can be a good way into the wonderful world of chamber music for younger audiences, and the Wigmore Hall’s new gambit of special student tickets for contemporary music paid off with the very different crowd there last night. It was rewarded with playing of the highest imaginative order from soloists in their own right: violinists Patricia Kopatchinskaja and Pekka Kuusisto, viola-player Lilli Maijala and cellist Pieter Wispelway.

Pianist Mitsuko Uchida's concentration, calm and grace under pressure are an inspiration. Towards the end of the first piece on her programme, played to a packed Royal Festival Hall last night, the quiet but insistent high-pitched screech of a fire alarm kept going off. Low voices on walkie-talkies at the entrances to the hall were also audible. Whatever the confusion they were sharing with each other, they were failing to lift it.

The silliness of the Last Night is really just a postscript to the penultimate night of the Proms, traditionally given over to a performance of Beethoven’s Ninth Symphony. It was a tradition restored yesterday evening when Alan Gilbert and the Leipzig Gewandhaus Orchestra returned for their second concert of the season. For anyone whose stomach is liable to turn at extrovert jingoism and excess, this was the perfect antidote.

“Ah now, I can’t promise you sun,” says a Scots lady-in-waiting of her native weather to a novice Englishwoman near the start of Rona Munro’s masterly James Plays. It’s the first of many references to make the audience laugh knowingly. Well, after four days of the worst weather Edinburgh Festivalgoers can remember, the sun came out yesterday morning. There’s no better place to be than the airy Queen’s Hall if you want an 11am recital of light and shade – and to say that of yesterday’s duo programme is an understatement.

The levels of refinement now exhibited by the Hallé, the stylishness and elegance of the playing, define the special relationship that they and Mark Elder have cemented over the last decade and a half. The opening bars of Berlioz’s Le corsaire came off the page like a manifesto for French sensibilities with rapier-like strings parrying airborne woodwinds like the most flexible of swashbuckling foils. The whole overture was so light on breath and string as to be positively balletic.

All kinds of narratives were at play in this Prom from the BBC Symphony Orchestra and its Principal Conductor Sakari Oramo - and perhaps the truly adventurous programmer might have double-deployed Rory Kinnear, dispassionately chronicling Stravinsky’s Oedipus rex, and taken us beyond the Overture and into the melodramas of Beethoven’s Incidental Music to Egmont.

We all love a good guitar riff and so a whole hour devoted to this one simple pleasure sounds like a surefire hit. BBC Four is the go-to channel for the rock‘n’roll documentary and this latest offering boasted a dazzling line-up including Brian May, Tony Iommi and Johnny Marr.
