Tradition – a choral spectacular for the penultimate night of the Proms – but with a twist – a youth choir and period instruments. Marin Alsop this evening led a spectacular Verdi Requiem, not least for the sheer scale of the chorus, the BBC Proms Youth Choir some 200 strong. The Orchestra of the Age of Enlightenment provided chacterful accompaniment, though sometimes struggled to compete, and the four soloists all delivered, particularly Tamara Wilson, here confirming her reputation as one of today’s leading Verdi sopranos.

You know what they say about men with big hands. Christian Thielemann has them, that’s for sure. Massive, meat-cleaving clappers, carving through the air. They give a pretty heavy upbeat too, and a generalissimo’s point and jab for a cue. If you’re a back-desk violinist in the Dresden Staatskapelle, you know when you’ve been Thielemanned.

Soft power in the shape of cultural ambassadors can go a long way. With a little help from its big guns in banking and industry, Germany has given this year's Proms no less than four of its major orchestras – from Leipzig, two from Berlin, and now from Dresden: all the more reason to wave those EU flags on a typically international Last Night in three days' time.

Daniel Barenboim is as distinctive as he is unpredictable. His considerable strengths – dynamism, passion, keen intellectual engagement – are balanced by some notable weaknesses – clunky tempo changes, lack of detail – but all configure differently in each performance. This Prom was a success largely for the fresh perspectives he brought to Mozart and Bruckner, both composers prone to stiffness and formality from less adventurous performers.

Gone, it seems, is the era of epic three-part Proms. Sunday afternoon's programme, partly billed as a children's hour, might have pleased pianist and pundit Stephen Hough, whose recent broadsheet plea for shorter concerts somewhat overdid the need (lunchtime events already cater to concertgoers in a hurry very well, and the Proms has its late-nighters too). But it left many of us wanting more, not just of Ravel in the second half but also of the distinctive Simón Bolívar earthiness, which was given free rein only in one spirited encore.

The BBC Proms is perhaps the only music festival in the world that would (or could) have programmed performances of Steve Reich in a Peckham car-park and Brahms by the Berlin Philharmonic within a few hours of each other. The audacity of it is glorious, the breadth exhilarating, and the fact that both sold out intensely heartening.

What do Boulez's Éclat, for 15 instruments, and Mahler's Seventh Symphony, for over 100, have in common? Most obviously, guitar and mandolin, symbols of a wider interest in unusual sonorities. But while Boulez aims, as often, for needle point precision, Mahler uses selective groups, at least up to his finale when he exuberantly exchanges night for day, to create peculiar and unsettling grades of chiaroscuro.

The BBC Proms is the largest classical music festival in the world – an event whose ambition, accessibility and breadth wouldn’t be possible without the Royal Albert Hall and its capacity of well over 5,000 people. But the building that makes this festival possible, that provides the space for the hundreds of Prommers who fill the arena each evening, is also its biggest curse. Its unwieldy, awkward acoustic is a problem that must be faced and resolved every night, and when it comes to Early Music, it’s a resolution that’s partial at best.
