If Don Giovanni is not the greatest opera ever written, it’s at least one of the very, very few that even in erratic performances have the capacity to seem it.

One thing’s clear from Irish National Opera’s bold championship of Vivaldi: he’s his own man when it comes to the stage, not some baroque generic, even if Bajazet is a pasticcio incorporating other composers’ music.

Some of Handel's late London oratorios, like the indestructible Semele, work well as fully staged operas. Others, usually the ones which swap mythology for the sacred, need dramatic help. Theodora is one of them, though Peter Sellars' now-legendary Glyndebourne production had a once-in-a-lifetime intensity. The singing if not the acting is more fitfully stunning here, but Katie Mitchell just about pulls off one of her most vivid and focused reimaginings.

One of the galvanizing wonders of the operatic world happened when David McVicar’s production of Mozart’s The Marriage of Figaro was new, back in 2006: the sight and sound of Royal Opera music director Antonio Pappano in seamless dual role as conductor and recitative fortepianist.

It had been a tense week, explained Jonathan Sells, the artistic director and bass-baritone of Solomon’s Knot, from the stage of the Wigmore Hall: unsure if the concert would go ahead, unsure who exactly would be able to perform, unsure if there would be anyone in the audience.

The world of the 17^th-century tavern is a long way from the contemporary concert hall. A quick glance at the scene in paintings by Jan Steen or his contemporaries shows us a joyful tangle of men and women, dogs, cats and small children, all engaged in a riot of drinking, dancing, brawling, music-making and love-making (occasionally even napping) while hens stroll officiously across the floor pecking up crumbs. It looks noisy, dirty and a jolly good time.

Peter Whelan is best known to Scottish audiences from his years of service as principal bassoon in the Scottish Chamber Orchestra.

The joint enterprise of soloist Jean-Efflam Bavouzet and conductor Gábor Takács-Nagy, with Manchester Camerata, in recording publicly all Mozart’s piano concertos alongside his opera overtures – with the project theme “Mozart, made in Manchester” – was rudely interrupted after 2019 by you-know-what. 

Rarely has the revolving door of opera twirled so efficiently.

It looked as if the Royal Opera might be trying to keep its distance with the first new production since lockdown.
