The only reasonable explanation for the all too belated arrival at the Proms of the SWR Baden-Baden and Freiburg Orchestra is that the festival’s house band, the BBC Symphony, is the one other ensemble reasonably entitled to claim the title of best orchestra for new music in the world. They came with a programme of Boulez, Ligeti and Bartók, 20^th century classics all, and well-tailored to their talents. Too little, too late, as it turned out, but what an evening they gave us.

There were two reasons why I didn’t return to the Albert Hall late on Friday night to hear Andras Schiff play Bach’s Goldberg Variations. The first was that one epic, Mahler’s Sixth in the stunning performance by Andris Nelsons and the Boston Symphony Orchestra, needed properly digesting. The other was that at Easter I’d heard Jeremy Denk play the Goldbergs in Weimar, and I wanted that approach to resonate, too – dynamic, continuous, revelatory, in a very different way from how I know Schiff approaches Bach.

When Bach set out in 1713 to write his Orgelbüchlein, or “little organ book”, he listed the titles of the 164 chorales that he wished to include in what was to be a compendium of organ preludes for use throughout the church year. In the event, he completed only 46, leaving 118 so-called “ghost” chorales, each with a given text and (in most cases) a melody – often an old Lutheran hymn tune.

Andris Nelsons and the Boston Symphony Orchestra have made the Shostakovich Tenth their calling card. Their recent recording of the work on Deutsche Grammophon has received universal acclaim, and now they're making their first European tour together, performing the symphony in London, Salzburg, Lucerne and Paris. It’s a great choice, a work that plays to all their strengths, conductor and orchestra alike. But this varied programme also demonstrated other facets of this versatile and increasingly distinctive partnership.

So here he was in town with his top American team, the already great conductor whose premature departure from Birmingham has left the players in mourning, unable to choose a successor yet, and whose insistence that it was too early to take up the coveted post of the Berlin Phil’s Principal Conductor blocked what should have been an obvious choice.

Two percussionists, two pianists, Adams, Reich and Bartók: Colin Currie and friends’ bracing morning recital at the Edinburgh International Festival made quite a pleasing change from the more traditional string quartets and vocal recitals elsewhere in the Queen’s Hall chamber programme. And it attracted quite a different audience, too – including many clearly there for the broader Edinburgh festival, unsure of what exactly they’d let themselves in for.

It's fitting that for its 50th anniversary the Edinburgh Festival Chorus should perform Berlioz’s gigantic Grande Messe des Morts. There is nothing in the large-scale orchestral repertoire in which the chorus plays so huge and significant a role – it sings throughout and the only soloist that Berlioz admits is a solitary tenor whose appearance in the "Sanctus" is almost apologetic.

It’s been glorious to hear so much Bach at this year’s Proms – most of it after dark, and still more of it for the most intimate of forces. On paper, the Academy of Ancient Music and BBC Singers’ Late Night concert of Bach choral works didn’t quite have the mystique of Ibragimova’s Solo Sonatas and Partitas, Schiff’s Goldbergs or Ma’s Cello Suites. In practice, though, it was clever piece of programming that came into its own in its Friday night slot, sending people home to the weekend on the very highest of musical highs.

When the Royal Opera House told Kenneth MacMillan that Mahler was unsuitable for ballet, he went – where else? – to Germany. Though the success of MacMillan's Lied von der Erde for Stuttgart Ballet led to its happy adoption into Royal Ballet repertoire, making ballet to Mahler still seems to draw German companies more than others – whether because the orchestras, audiences, or state subsidies are better, who knows?
