And so Wotan’s ravens flew home and at the twilight’s last gleaming the immortals were consumed by fire and water. All was finally and irrevocably redeemed by the power of love, and the most beautiful of all the leitmotifs in Wagner’s Ring rolled out across the Albert Hall like a benediction. It was a defining moment in Proms history, no doubt, and was greeted with a few moments of perfect - and I mean perfect - silence.

Such has been the justifiable flow of superlatives this week about the Berlin Staatskapelle's Ring conducted by Barenboim, the centrepiece of the BBC Proms' Wagner bicentenary celebration, it would have been easy to forget that the 2013 Proms season contains not just those four, but seven complete Wagner operas.

The transformative power of the Royal Albert Hall at Proms-time never ceases to amaze me.

JThis year’s Proms have been accompanied by an unusual choral drone, a monotony of voices whinging about the prodigious heat at the Albert Hall. For one night only no one was complaining as the temperature gauge went up to something like 111. You’ve heard of the Hollywood Prom and Comedy Prom, the Gospel Prom and the Dalek Prom. As a troupe of classical Spanish dancers swished and swirled, stomped, strutted and thrust to pulsating Hispanic music, here was something never before seen: the Erotica Prom.

Most of us could compile soundtracks to our lives. We’d probably save our favourite songs and pieces for the worst bits. Pianist James Rhodes was sectioned in his twenties and maintains that a visitor who smuggled in an iPod stuffed with classical music helped to save his life. He’s refreshingly candid though, admitting slyly that “listening to a piece of Bach isn’t going to fix everything".

Things may be falling apart, a storm now rages but new broods of humans and demigoddesses have been fathered by chief god Wotan, who has undergone a Doctor Who like transformation from Iain Paterson into Bryn Terfel.

Swimming around in the Rhine is what most of us wanted to be doing on the hottest day of the year. A cooling, riverbed low E flat from Daniel Barenboim’s Berlin double basses, and then the staggered horn entries announced we were going to be in the finest sonic hands for two and a half hours  – or nearly 15, if the colossal Proms Ring is to be accounted in its full, four-night glory.

Yes it’s Wagner Week at the Proms, and just up the road in the Royal Albert Hall there are dwarves and giants enough to rival Comic Con, and enough noise to silence any objection and obliterate all competition. Even the greatest of musical excess needs a counterbalance, however, and it comes in the form of the Proms’ chamber music events. Saturday’s matinee and yesterday’s lunchtime concerts couldn’t have been in greater contrast to the mighty Ring, offering up two miniature musical portraits.

Youth orchestras do well at the Proms. Built to the same sprawling scale as the Royal Albert Hall, their energy is also a natural fit for the relentlessly enthusiastic Proms audience. The Gustav Mahler Jugendorchester, the Simón Bolívar Youth Orchestra, the Aldeburgh World Youth Orchestra, our own National Youth Orchestra – year after year we marvel at the skills of these young musicians and come away with new demands to make of our professional ensembles. But last night the newly formed National Youth Orchestra of America showed their inexperience.

It’s a dilemma of anniversary years, and never more so than with Wagner’s and Verdi’s 200^th birthdays: do you stick to the masterpieces or try and bring the rarities to life? No-one would have minded, I suspect, if Antonio Pappano and the Accademia di Santa Cecilia forces he has raised to the level of one of the world’s great ensembles had reprised their peerless Verdi Requiem. It was unfortunate, then, if some of us sat with interest through unusual fare wishing for better alternatives in every case.
