A day after John Eliot Gardiner and wandering violist Antoine Tamestit had converted the Royal Albert Hall into a sonic map of Hector Berlioz’s Italy, conductor Peter Oundjian and his full-strength divisions transported us to the Western Front.

How do you make your mark in a crucial last week after the Olympian spectaculars of Kirill Petrenko's Proms with the Berlin Philharmonic?

Crazy days are here again – many of us are lucky not to have been born when the last collectve insanity blitzed the world – and nothing in Shostakovich seems too outlandish for reality. On the other hand, there's a growing movement to liberate his symphonic arguments from rhetoric and context.

Did the earth move for us? You bet. Sunday’s two Proms brought fabled visitors to the Royal Albert Hall – first the Boston Symphony Orchestra, then the Berlin Philharmonic for their second concert – but our august guests dispensed with all polite formalities.

Setting aside any reservations about a slight overall timidity in repertoire choices - no problems with that last night - this year's Proms have worked unexpectedly well, above all with their weekend strands.

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.

It was the C major Prelude and Fugue from this second book of Bach's The Well-Tempered Clavier, not its more familiar counterpart in Book One, which found itself tracked on a gold-plated disc inside Voyager I to reach whatever intelligent life there may be outside our solar system. Surely more interesting, though, is the universe within the minds of certain exceptional individuals – in this case not just that of the composer, which remains unfathomable.

“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.

1944 was one hell of a year for Bernstein the composer, with a perfect ballet and a near-perfect musical sharing a general theme of three sailors loose in New York, but nothing else, in their boisterous originality. Perhaps their only equal among Bernstein's works - more contestably – is MASS of 1971, surely his biggest and most resonant score, but hardly a candidate for comparable classicism.
