Jean-Philippe Rameau wrote Hippolyte et Aricie in 1733 at the age of 50. It was his first opera and his greatest. In its five acts, its visits to the woods of Diana, the groves of Venus, the fires of Pluto and the domestic meltdown in the house of Phaedra, is some of the most assured, inventive and stylish music ever written for the stage. As operatic debuts go, it is a miracle. 

It may have taken Sarah Connolly a decade or two, a detour to choral singing and a serious flirtation with jazz, but the British mezzo-soprano has most definitely arrived at full-blown National Treasure status. Perhaps it was her career-changing Xerxes in Nicholas Hytner’s 1998 Xerxes for English National Opera that marked the start of her reign, perhaps her 2005 Giulio Cesare for Glyndebourne.

There are Handel operas where you wait impatiently for the handful of truly original set-pieces to light up the action, hoping the singers are equal to their challenges. One such is surely Siroe, Re di Persia, bravely staged at the Göttingen Handel Festival the other week. Others like Imeneo sparkle with genius and personality in virtually every number, musically if not dramatically the equal of a Shakespeare late romance.

Let me confess: I had to return to lovely Göttingen as much for the frogs as for the Handel. Puffing out their throats like bubblegum, the amphibians' brekekekek chorus in the ponds of the great university’s botanic gardens actually made a more spectacular showing, in my books, than the main opera of this year’s Handel Festival, the 93^rd, with its canny theme linking the German honorary Englishman with the Orient. Not even the effervescent Laurence Cummings in his second wonderful year as festival director could kiss the mostly humdrum Siroe, Re di Persia into a prince.

The return of the Lufthansa Festival of Baroque Music to London each year always heralds the beginning of summer. Granted this beginning is usually damp and decidedly chilly, but there’s a hopefulness in the air that things might be about to change. And this sense of hopefulness doesn’t end with the weather. Under Lindsay Kemp the festival’s programming is reliably wide-ranging and joyful, a proper celebration of the landmarks and the paths-less-trodden of the baroque repertoire.

As a self-taught chemist, innovative industrialist, a businessman who exploited and developed new means of distribution and marketing, an anti-slavery campaigner and a man dealing with his own disability, the Staffordshire potter Josiah Wedgwood was an important 18th-century figure, a pioneer whose achievements still resonate. But a genius?

If ever there was such a thing as a safe pair of pianistic hands then they would belong to Norway’s Leif Ove Andsnes. There’s a cool, patrician control to everything he does that speaks to thorough preparation, careful interpretative choices and immaculate technique. Thrill-seekers and risk-takers may want to look elsewhere, but for everyone else Andsnes offers the chance to hear cleanly through to the skeleton of a work.

Bach for breakfast, lunch and supper. That in essence was what yesterday's Bach Marathon was about. You can do that with Bach - have him flowing from the taps. Nothing new in this for those of us who experienced the Bach Christmas a few years back on Radio Three, when every note was piped over the airwaves for breakfast, lunch and supper for 10 days solid. Nothing very marathon-like about any of it, though, either. The day’s performances couldn’t have been further from a challenge to sit through or listen to. 

A Leipzig church is surely the place we’d most like to be for Bach on Good Friday. Never mind: the Barbican Hall is kinder to the best period instrument ensembles than it is to big symphony orchestras. Better still, having sat stunned and weepy for a good few minutes at the end of this performance, I’m happy to evangelise and proclaim that no better team could be assembled anywhere for the original 1724 version of this world-changing musical Passion.
