You get a lot of notes for your money in a two-piano recital - especially when seven pianists share the honours for two and a half hours' worth of playing time. Well, they did call it a marathon, crowning the London Piano Festival so shiningly planned by Katya Apekisheva and Charles Owen, and the baton passed seamlessly from two pairs of hands to the next.

There must be something of a beauty parade going on in Liverpool now that Vasily Petrenko has called time on his tenure at Philharmonic Hall.  After all, someone will need to step into his shoes from 2021 after he departs for the Royal Philharmonic Orchestra. It was refreshing, therefore, to welcome Anu Tali to conduct the Royal Liverpool Philharmonic, making her debut with the orchestra.

Sibling incest among the symbolic clutter of the Royal Opera Ring on Wednesday, last night necrophilia and a bit more incest – mother and daughter this time, courtesy of the director's imagination – in a stone-cold ENO Salome. Adena Jacobs' credentials were promising, not least her time at Sydney's cutting-edge Belvoir Theatre.

This Prom had three pieces from times of social crisis, although only one faces its crisis head on. Stravinsky’s Rite of Spring hides its pre-war angst behind a story of pagan Russia while Ravel’s post-war desolation is danced in decadent Viennese waltz time in La Valse.

Can we ever really know the passion that brought our parents together? By the time we are old enough to hear the story of how they first met, that lovers’ narrative has frayed in the telling and faded in the daily light of domestic familiarity.

“What drivel! What nonsense! What escapist Techicolor twaddle!” No, not a description of Wallis Giunta’s scintillating BBC Proms at Cadogan Hall recital, it’s a lyric from “What A Movie”, Leonard Bernstein’s outstanding stand-alone number from his one-act opera Trouble In Tahiti. Narrating the story of a ridiculously torrid movie the heroine has sat through, Giunta joyously inhabited its every moment and delivered it with complete theatrical assurance.

The Edinburgh International Festival scored quite a coup in securing the services of Bernstein protégée Marin Alsop and the Baltimore Symphony Orchestra on the very day of the great composer/conductor’s centenary – and for the festival’s penultimate concert of 2018.

The most famous face in musical history, and perhaps the instigator of modern culture as we know it; he truly was the King. But for a documentary focused on such an icon, The King touches very little on Elvis Presley the man.

A slow tracking shot over the gassed corpses of soldiers, their masks having failed the ecstasy of fumbling, opens The Guardians. This French art house film would perhaps have been better served by the English title The Caretakers; it's closer to the original French meaning and would have made it less likely to be confused with a superhero movie.

This should have been the third much-anticipated Prom of the City of Birmingham Symphony Orchestra's inspiring communicator-in-chief Mirga Gražinytė-Tyla. She's now on maternity leave. So those of us who hadn't experienced Ludovic Morlot live before had a chance to witness what a splendid moulder and shaper he is, here in a skilfully co-ordinated all-French programme.
