Usually, anyone bringing tuberculosis and transgression to the regional centres of Woking, Norwich and Milton Keynes would meet redoubtable opposition. In the case of Glyndebourne’s new touring production of La traviata, that would be a shame, because this is a lean, powerful version that reaches straight for the heart and gives it a good squeeze.

Tim Albery’s production of Monteverdi’s The Coronation of Poppea takes plenty of liberties. There are moments when you scratch your head, quietly sigh, and think about your interval drink, or what you’ll eat when you get home.

Monteverdi’s L’Incoronazione di Poppea is an opera with a one-track mind. The music throbs and pulses with dancing desire, suspensions and elaborate embellishments defer gratification, while recitative is poised constantly on the edge of melodic climax. Desire is everywhere, from the innocent flirtations of a young courtier and his lady, to the hopeless love of Ottone and of course the knowing, mature passions of the Emperor Nerone and his mistress Poppea. Without it, there’s a void at the core of the opera – a void no amount of fine singing or playing can fill.

So easily parcelled up as a master of opera buffa, Rossini is a composer who constantly surprises by the emotional and intellectual range of his best work. William Tell, which opened WNO’s current season three weeks ago, is a major progenitor of Verdi, even arguably Wagner: grand opera devoid of what Wagner himself called effects without causes.

So now it’s Minnie Get Your Gun from the director who brought us the gobsmackingly inventive Young Vic Annie (as in sharpshooter Oakley, not Little Orphan). Richard Jones’s subversive but still very human take on Irving Berlin discombobulated its American support and never made Broadway; but there’s little here that would rock the steadily progressive Met (home of La fanciulla del West’s 1910 premiere, with Enrico Caruso as “Dick Johnson” aka quickly repentant bandit Ramerrez).

2014 is the 250^th anniversary of the death of Jean-Philippe Rameau, France’s baroque giant and maverick. To say that the UK celebrations have been muted is to put in generously, reconfirming a national trend that has long sidelined this repertoire in favour of more familiar Italian and German contemporaries. So it was especially good to see the Wigmore Hall full for an anniversary concert from instrumental ensemble Les Paladins and soprano Sandrine Piau.

At the end of last night’s giddy, triumphant concert at the Barbican, Joyce DiDonato was presented with a bouquet by a member of the audience. It included, among more conventional flowers, a tomato plant, complete with ripe tomato. That says it all really. Just imagine Netrebko, Gheorghiu or even Bartoli faced with a tomato and the confusion that would ensue.

It’s only a few days since I was remarking, à propos the WNO revival, that Carmen usually survives its interpreters. Now WNO’s humble neighbour, Mid Wales Opera, are proving the same point, but in a more positive spirit, by touring a new production by Jonathan Miller, with a vastly reduced orchestra, a cast of fourteen including chorus, and a set (Nicky Shaw) made up of moveable stagings cleverly lit (by Declan Randall), like some highly simplified Chirico. Once again, Bizet comes through, not exactly enhanced, not always idiomatic, but as enjoyable as ever.

Popularity is all very well, but it can be a poisoned chalice. Braving the umpteenth revival of Carmen at WNO (original directors Patrice Caurier and Moshe Leiser, revival director Caroline Chaney), I began to experience that sense of weariness that sometimes afflicts the dutiful end of the repertoire: Bizet’s masterpiece along with the relentless Butterflies and Toscas, the Figaros and Barbers. That feeling that the work and its myriad devotees will somehow get us through in the absence of anything resembling artistic necessity.

Nicholas Hytner’s 1988 Magic Flute may have trilled its last at English National Opera, but judging by the wit, the joy and the energy on display last night it would be absolutely criminal to put the director’s even more elderly Xerxes out to pasture – the show that brought Handel back into fashion when it premiered in 1985.
