Look what's popped up on Youtube: complete audio of Jonas Kaufmann's Winterreise recital at the Konzerthaus, Vienna, 6 April 2013. Helmut Deutsch is at the piano. Apparently JK was not feeling on best form just then - he was recovering from the lurgy that knocked him out of two Vienna Parsifals. It's remarkable nonetheless.

Prepare to listen by getting yourself a cuppa, a box of hankies and a DO NOT DISTURB sign.

(UPDATE, 5.40pm: An appreciative reader has just tweeted to remark that this is good alternative listening for anyone trying to avoid the Eurovision Song Contest tonight...)

A starry cast is set to make waves in La Donna del Lago at Covent Garden. I had a brief chat with the director, John Fulljames, about why he thinks Rossini's rarity is - well, rare.

He thinks it's all to do with the difficulty of the vocal writing; as for the story, it's at the heart of that weird 19th-century idea that Scotland is the most romantic place on earth - a form of cultural nationalism that was invented, as he explained, by Sir Walter Scott. Might it yet prove to be a favourite opera for the Scottish National Party? We'll see... anyway, one hopes they can't go far wrong with Joyce DiDonato and Juan Diego Florez out front. http://www.independent.co.uk/arts-entertainment/art/features/la-donna-del-lago-at-the-royal-opera-house-starry-cast-all-set-to-make-waves-8619557.html?origin=internalSearch

Here's my piece from yesterday's Independent about what happened to Glyndebourne during World War II. It was transformed into a centre for children evacuated from London's east end - and that history has now inspired a new staging of Strauss's Ariadne auf Naxos, which opens tomorrow. I talked to its young director, Katharina Thoma, whose first UK production this is.

Meanwhile, we hear that the cats are back in Falstaff...there are calls for the cat manipulator to take a bow, but naturally the truth is that the ginger one is Solti, who sneaks to Sussex and back by private cat-jet when we aren't looking.

Full info on Glyndebourne here.

And to make this a real Friday Historical, here is footage of Figaro from Glyndebourne 1956, with Sena Jurinac as the Countess and Sesto Bruscantini as the Count.
