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.

Music-lovers who normally balk at the sight of national colours in a concert hall would surely have forgiven the little Estonian flags – in stripes of blue, black and white – that waved happily at the conclusion of this Prom.

When did this weird mix-tape fashion take root at the Proms?

Unanticipated miracles happen every summer in the quiet paradise of Estonia's seaside capital. The first this year came as a total surprise. Having got off the afternoon coach from Riga last Monday and dumped bags at my villa base in Pärnu's garden zone, I headed back into town for the first event.

In West Side Story, those great, familiar songs just keep on coming. Already by the end of the first half an hour, there have been “The Jet Song”, “Something’s Coming”, “Maria”, “Tonight” and “America”, and there is no shortage of them still to come.

In the beginning, Sir Antonio Pappano created a little chaos of his own.

It was all about the acoustic. Well, almost. Disregarding the awe-inspiring grandeur of the Royal Albert Hall, there’s a school of thought that believes the Proms is the world’s greatest concert series in the world’s worst hall. Why? Because its problematic acoustic is so ungovernable.

The heart of Prom 33 was Brahms’s massive German Requiem, a piece that eschews Christian dogma and Day-of-Judgment terrors for a humanism focusing on consolation of the bereaved.

Prom 31 featured an American orchestra playing an all-American programme – until the final encore dived thrillingly into a completely different musical tradition. But one of the principal features of American music – its joyous risk-taking – was undermined by conductor Osmo Vänskä’s cautious tempos, and the orchestral playing only periodically caught fire.
