The Concertgebouw Orchestra of Amsterdam began their two-concert visit to the Barbican with a crowd-pleasing programme: Brahms and Beethoven. We are used to hearing the pinpoint precision and transparent textures of the London Symphony Orchestra from the Barbican stage, but the Concertgebouw has a different sound.

He was indeed "one of the greats" among conductors, as theartsdesk's Gavin Dixon put it in reviewing Mariss Jansons' January visit to the Barbican, and remains so by virtue of his recordings.

How do you get to heaven, especially if you need to reach the pearly gates by way of the earthbound acoustics of the Royal Albert Hall? With Chief Conductor Daniele Gatti as their spirit guide, the sumptuously arrayed pilgrim band of the Royal Concertbegouw Orchestra from Amsterdam sought different routes in the centrepieces of their pair of Proms.

Time was when the principal conductor of a top orchestra could afford to refine mastery of a small and familiar repertoire, covering a century and a half of music at most. The rest he (always he) would leave to loyal or youthful lieutenants. The days of such podium dinosaurs are numbered. The likes of Valery Gergiev, Mariss Jansons and Riccardo Muti are outflanked by colleagues, mostly a generation or two younger, who have been trained to view the entire history of Western ensemble music – at least three centuries’ worth – as the right and duty of an orchestra to promote.

The last night Haitink conducted at the Royal Opera House as musical director the staff wheeled on a moped as a leaving present. Ever since, his conducting has been inextricably linked to that mode of transport in my head. With Haitink, music-making has always seemed to be about getting from A to B in the most dependable, unfussy and often uninspiring way possible. For years, I haven't been able to see the point of him at all.

I half expected to hear someone on the platform call out “Is there a doctor in the house?” For Mariss Jansons, principal conductor of the Royal Concertgebouw Orchestra, and esteemed beyond measure, didn’t look well during this concert, the second in the orchestra’s current Barbican residency. Drained from his exertions during Strauss’s Also sprach Zarathustra, he left the platform weary and grey. The following interval was seriously extended.
