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.

“My honest instinct,” says Jim, the hero of Bruce Norris’s The Low Road, “is one of resentment.” And while this contemporary fable of industrious bees, aka capitalist speculators, is set in the past, and is full of good jokes, it is also laced with emotions that are a tougher sell. Here a humorous tale of a life of entrepreneurship comes hand-in-hand with some satire that is bitter as well as being funny.

You’d not expect Einstein to have daubed Amadeus’s Ninth Piano Concerto with the label “Mozart’s Eroica”. The really famous one didn’t : that piece of punditry came not from Albert the Great but Alfred the (musicologist) Lesser. Embarrassingly, the OAE’s publicity didn’t seem to know the difference. Anyway, by advertising this concert with Alfred’s tag at its head, the intention was surely to highlight the shock of the new in all three works played and/or conducted by András Schiff.

How do you solve a problem like Medea? Euripides’ baby-killing, hell-invoking sorceress is one of literature’s most terrifying and unfathomable creations – a woman capable of murdering her own children just to watch their father’s pain. Yet with the blood on her hands now centuries-old, Medea continues to work her grim enchantments on artists. No fewer than eight operas (and an almost equal number of plays) have staged her story, but have any really got to grips with the psychology of tragedy’s wickedest witch?
