Anja Kampe is electrifying in a top line-up for Wagner's second Ring opera

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.

Bryn Terfel by no means the only treasure on board top Swiss ship

Much more regularly than the seven years it takes the Flying Dutchman's demon ship to reach dry land, the Zurich Opera steamer moors at the Southbank Centre. None of its more recent concert performances up to now has branded itself on the memory as much as its 2003 visit, when chorus and soloists stunned in Wagner's Tannhäuser.

First Night of the 2012 Proms

FIRST NIGHT OF THE PROMS: An all-British start to the Proms with four conductors, not much flag waving, and limited joy

An all-British start to the Proms with four conductors, not much flag waving, and limited joy

Two weeks to go to the Olympics, of course, but the Proms Olympics – 84 concerts in 60 days – have already taken off, with Britain placed first, second, third and fourth. For last night’s First Night concert was one where everything except Canadian singer Gerald Finley was British: the composers, the conductors (all four of them), the orchestra, certainly the weather.

Welsh Week: Dinefwr, Adain Avion, Llangollen, BrynFest

WELSH WEEK: A new literary festival, an old singing festival, London 2012 moves to the Valleys, Faenol moves to London

A new literary festival, an old singing festival, London 2012 moves to the Valleys, Faenol moves to London

This Friday afternoon at five o’clock, the National Poet of Wales Gillian Clarke will recite a new poem and initiate a seismic week of Welsh cultural exploration. The inaugural Dinefwr Literary Festival will bring writers and musicians from Wales and beyond to a National Trust house and park in Carmarthenshire. Unlike other literary festivals in Wales – notably Hay and Laugharne – this one will straddle the border between English and Welsh.

THEARTSDESK AT HAY 25: What have Shakespeare, ancient Greece and history ever done for us?

What have Shakespeare, ancient Greece and history ever done for us? The 25th festival answers a lot of questions

To each their own Hay. The Roman encampment that is the modern-day literary festival, circled by pantechnicons and trending in the Twittersphere, looks very much like a monomaniacal content provider for all comers. Astroturf walkways deliver the cagouled hundreds and thousands to events in tents with clockwork regularity. But the reality is, of course, that no two experiences of Hay are alike. A bit like snowflakes.

Tosca, Royal Opera

This revival is about a soprano, a tenor, a baritone - Opera with a capital O

Tosca-at-Covent-Garden is a commodity, like bacon-for-breakfast - a pricier commodity, to be true, at officially up to £229.50 a seat, but in both cases people want to get what they expect. For the final performances next month in this summer revival, with the megastars Angela Gheorghiu, Jonas Kaufmann and Bryn Terfel, all seats are sold, with touts on eBay offering a pair of amphitheatre seats at bids over £300.

Stephen Sondheim at 80, Royal Albert Hall

A slick and stylish Proms spin through some of the music man's greatest hits

Everybody in the business says don’t think Sondheim is easy. I’ve seen galas where big names stumbled in under-rehearsed numbers, and last night Bryn Terfel and Maria Friedman slipped and almost fell on the same banana skins that had done for them in a hastily semi-staged Sweeney Todd. Not enough to matter, though, and they rightly brought the house down. And the show as a whole?

Die Meistersinger von Nürnberg, Welsh National Opera, Cardiff

TAD AT 5: DIE MEISTERSINGER, WNO Bryn Terfel excels in brilliant Wagner production

Bryn Terfel excels in Richard Jones's clear and brilliant Wagner production

Only those who think the burnt-out question of Wagner and the Nazis can still be brought to bear on his operas could be disappointed by Richard Jones's life-enhancing new production. Not a swastika in sight, not a hint of anti-semitic caricature for the fallguy who was never intended for it in the first place, only affirmation of the opera's central message that great art can bring order and understanding to society.

Bryn Terfel, Royal Festival Hall

Bad boys of opera are grist to Welsh star's mill

Bryn Terfel is a good guy. I know; he never forgets a face, and I’ve seen him making the tea for the entire team at a recording session – no one-off, they assured me. Yet the nature of the bass-baritone beast is given over to more villains than noble souls. The "bad boys" of opera and musical theatre are grist to Terfel’s satanic mill in his latest CD-linked tour. Although inevitably given the demands of live performance there’s less than meets the ear on the disc, Bryn as dark god in concert gives far more than those recent short-shrifting divas Fleming and Gheorghiu.
