How to respond to Mahler? That was the challenge set by the London Symphony Orchestra to Edward Rushton when they commissioned him to write an opener for this programme. Rushton’s response was to take a story from a biography of Alma and spin it into an orchestral fantasy. The story goes that Alma, listening to Gustav compose the Fifth Symphony, complained about the excessive orchestration, which he then dutifully toned down.

Last night at the Royal Ballet was, emphatically, laser-free. The combination of Afternoon of a Faun (1953) and In the Night (1970) by the great American choreographer Jerome Robbins, with a repeat of Kenneth MacMillan's 1965 Song of the Earth, performed earlier this season in a different triple bill, is your archetypical safe bet, presumably calculated to soothe any ruffles that might have been caused by Wayne McGregor's ambitious Virginia Woolf opus. The Royal Ballet ought to have been able to do these mid-century classics standing on its collective head.

“Songs of Vienna” by the Britten Sinfonia turned out to be a concert of chamber works, with never more than six performers on the stage at any time. It was built around two appearances by the Canadian soprano Barbara Hannigan, who performed pieces with voice by Chausson and Schoenberg. They are clearly part of her core repertoire, and she sings them with passion and from memory.

After the second piece of last night's triple bill, Hofesh Shechter's Untouchable in its world premiere, my friend asked me why it had been put on the programme with the first piece, George Balanchines 1946 Four Temperaments. He wondered if there was some structural or thematic connection that he had missed between the two wildly different pieces. The Balanchine speaks obviously to the bill's last item, Kenneth MacMillan's 1966 Song of the Earth; both pair a cool neoclassical choreographic idiom with deeply felt but vaguely expressed melancholy.

Even by trumpeters’ standards, Håkan Hardenberger is a flamboyant figure. He sports a sharp, tailored suit and a wing-collared shirt, and his stage presence is all swagger and pomp. HK Gruber has captured his spirit perfectly in his jazzy, experimental trumpet concerto Aerial, which has become the trumpeter’s calling card. That proved the highlight of the evening here, though, as it was followed by a lacklustre Mahler Five, a rare disappointment from the usually reliable conductor Andris Nelsons.

It’s all over: the final note of the Berliner Philharmoniker’s London Residency, for which many music-lovers bought tickets about a year ago, has risen into the ether, leaving most questions concerning Sir Simon Rattle’s future plans as yet unanswered. Following a red-hot Sibelius cycle at the Barbican, the Berliners came over to the Royal Festival Hall to complete the weeklong residency with Mahler’s Symphony No 2, which sold out twice on two consecutive evenings.

The Simón Bolívar orchestra is the musical answer to the question “Would you like to supersize that?” A youth orchestra in bulk, if no longer in name, the ensemble has made a signature of its heft, making repertoire work on its own terms rather than adjusting itself to fit. On Thursday night, full-fat Beethoven and Wagner that threatened to overspill in the generosity of their gestures, so how would the orchestra fare with Mahler’s mighty Fifth Symphony?

There have been legendary conductors, and then there was Herbert von Karajan. He was a colossus of post-World War Two classical music, equipped with fearsome technical mastery allied to a vaguely supernatural gift for extracting exquisite sounds from orchestras. But that wasn't all. An expert skier with a passion for high-performance cars and flying his own jet, he was as charismatic as a movie star or sporting idol.

When I entered the light and spacious chief conductor’s room in Bamberg’s Konzerthalle, Jonathan Nott was poised with a coloured pencil over one of the toughest of 20^th century scores, Varèse’s Arcana. He thought he might have bitten off rather a lot to chew the day after that night’s Bamberg programme of Jörg Widmann’s Violin Concerto, Strauss’s Eine Alpensinfonie and a new commission as part of the orchestra’s new Encore! project, David Philip Hefti’s con moto.
