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.

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.

There seems no limit to the sheer creativity that fizzes from Iván Fischer and his Budapest Festival Orchestra. For their second night at the Proms, packed out this time, the theme was the meeting of classical and Gypsy musical traditions.

Two heartening facts first. Iván Fischer's much-loved crew remains one of the few world-class orchestras with an individual voice, centred on lean, athletic strings adaptable to Fischer's febrile focus (perfect for Enescu and Bartók, not quite so much for Mahler).

Who is the greatest British conductor in charge of a major orchestra? It's subjective, but my answer is not what you might expect. Jonathan Nott has done all his major work so far on the continent. He left the Bamberg Symphony Orchestra in excellent shape to another of the world's best, Jakub Hrůša; and now he is, as we learned from two long-term players in the Proms Plus talk, liked and respected across the board at the Orchestre de la Suisse Romande.

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.

The days are long gone when a Proms gig by Daniel Barenboim and his West-Eastern Divan Orchestra felt like a life-changing visitation by a major prophet.
