Three “little greats,” as Opera North might put it, proved just the thing to cleanse the palate in a quiet place the afternoon after the LSO/Rattle Stravinsky trilogy.

“Next he’ll be walking on water,” allegedly quipped a distinguished figure at the official opening of Simon Rattle’s new era at the helm of the London Symphony Orchestra. Well, last night, with no celebratory overload around the main event, the homecomer was flying like a firebird, and taking a newly galvanised orchestra with him, at the start of another genuine spectacular.

For his monster concerts in 1840s Paris, Berlioz took pride in assembling and marshalling a "great beast of an orchestra". At the Barbican on Sunday night, the LSO filled the stage and fitted the bill.

“Keep here your watch, and never part.” There was a strong symbolism of standing and singing together in the last moments of the Grenfell Tower Benefit Concert. After singing the Lament of Purcell's Dido, Christine Rice made her way back slowly through the orchestra to join the choir. All 150 participants in the concert, operatic stars, young singers, conductor, a special orchestra assembled from various London orchestras joined in for the final chorus of Dido and Aeneas. All had given their services for free to support charities helping Grenfell Tower survivors.

After all the talk and anticipation, at last some music. Simon Rattle took up the reins of the London Symphony Orchestra last night – as its first ever “Music Director” – with a programme dedicated to home-grown composers whose lives span the lifetime of the orchestra.

Every 21st birthday deserves a party, and the Bridgewater Hall in Manchester celebrated the anniversary of its opening with a weekend of fun and "access" events, ending with a recital by four pianists on its four Steinway pianos – playing them all at once, in eight-hand arrangements.

The Last Night of the Proms is always a beautifully choreographed event, and this year’s was no exception. The format changes little, but each year a new selection of works is chosen to fill the slots. The BBC Symphony Orchestra, always the backbone of the season, somehow manages to sound fresh for their final outing.

The Vienna Philharmonic makes a beautiful sound, no question about that: the question is what to do with it. Michael Tilson Thomas has some ideas, but they are mostly low-key. He is currently touring with the orchestra, and seems to have been chosen as a safe pair of hands, offering elegant and lyrical interpretations, but without any extravagance.

Outlines of a real face had begun to emerge in Daniel Harding’s conducting personality. His youthful rise to the top initially yielded neutral concerts with the LSO and a glassy, overpraised recording of Mahler’s Tenth in the Deryck Cooke completion with the Vienna Philharmonic. But then I heard a supple, intensely lyrical Brahms Third in the Concertgebouw and what came across on CD as a fine live interpretation of Mahler Six from Munich.

Amazingly, last night Sir András Schiff scored a Proms first with his performance of Book One of Bach’s The Well-Tempered Clavier. Never before has even half of the sublime and seminal “48” taken the Royal Albert Hall stage in unmutilated form. The WTC could have found no better advocate.
