Two suns, two moons, two Philharmonia leaders sharing a front desk, two aspirational giants among Richard Strauss's symphonic poems bringing the number of players, in the second half, to 134. Who’d have thought we’d be witnessing such phenomena when, contrary to what the orchestra’s CEO claimed at the start and the unmasked half of a packed audience seemed to think, we haven’t even reached the “post-Covid era”.

This lively interpretation of Richard Strauss’s opera within an opera provides a feast for the senses as a musical highlight of the Edinburgh international Festival.

Whatever else happens on the country opera scene this summer, the golden rose award for sheer chutzpah goes to the ever-ambitious Garsington team in pulling this off in no small style. Planning any production of Richard Strauss and Hugo von Hofmannsthal’s intricate 1911 “comedy for music” is daring at the best of times; in the still-shaky Covid era, the decision to go ahead might have seemed foolhardy.

Venus, Cupid, Folly and Time stalk this haunting dream of a Rosenkavalier. The love games of teenager Octavian and his experienced mistress the Marschallin are sexy and plausible; the comedy of ridiculous Baron Ochs keeps a low profile, but stays real and turns out funny in unexpected places; a winged old gentleman (Ingmar Thilo) embodies the second and fourth manifestations. Does he make up for all the detail in the minor and non-singing roles shed by director Barrie Kosky?

The second of the Hallé’s Winter Season concerts-on-film is scarcely less ground-breaking than the first. But this time we are in the orchestra’s second home, the former church now extended to be Hallé St Peter’s in the regenerated part of Manchester's city centre. The same skilful use of camera techniques to show a socially distanced ensemble, with Sir Mark Elder as conductor and, this time, Roderick Williams as vocal soloist, makes satisfying visuals to go with arresting sound.

The BBC Scottish Symphony Orchestra’s Prom was a sombre contribution to an otherwise upbeat season. The mood was reflective – looking back on lockdown. The concert was given at City Halls, Glasgow, where the privations of social distancing were also more keenly felt than in the Albert Hall.

So much for the assertion that nowhere in the world would be staging the big Strauss and Wagner operas for the indefinite future. With a combination of lavish funding and good pandemic management on Austria's part, it’s been possible in Salzburg.
