There’s a grail, but it doesn't glow in a mundane if perverted Christian ritual. Three of the main characters have young and old actor versions and the “wonder-working spear” is a knife in a Cain and Abel story superimposed on Wagner’s myth (as if that wasn’t complicated enough). Kundry, whom the composer defines as literally flying between “good” and “bad” worlds, enters primly in the first two acts bearing a tea-tray.

Transcendence is everywhere in Mahler’s most ambitious symphony, from the flaming opening hymn to the upper reaches in the epic setting of Goethe’s Faust finale. You’d think no visuals could match the auditory phantasmagoria, just as dance, music and design flunked the essence of Paradiso in the Royal Ballet’s The Dante Project. Mahler does compose a kind of concert opera in Part Two, though; sound, movement and image accorded well.

Thomas Adès: Orchestral Suites London Philharmonic Orchestra/Thomas Adès (LPO)

When Vladimir Jurowski returns to what used to be “his” London Philharmonic Orchestra, you’d better jump. I would have done on Wednesday had I been able to get to his heady mix of Russian and Ukrainian rarities; luckily I could on Saturday night, because an outwardly standard programme of early 19th century works proved perfect, raising Schumann’s much-denigrated Violin Concerto to the level of Beethoven’s Coriolan Overture and Schubert’s “Great” C major Symphony.

When Vladimir Jurowski planned this typically unorthodox programme, he could not have known that a disaster even greater, long-term, than 9/11 was going to befall the USA two days after the concert. There is no bad time for a tricky commemoration of the World Trade Center attacks, but close to a presidential inauguration would have been right whatever the outcome. As for an 18^th century “Mass in Time of War”, clearly Ukraine and Gaza would still be on the agenda.

Ravel: The Complete Works with Piano François-Xavier Poizat, Philharmonia/Simone Menezes et al(Aparté)

If there was ever a time for the inevitable "Rach Three” (piano concerto, not symphony) in the composer’s 150^th anniversary year – and I confess I dodged other occasions – it might as well have come in the fresh and racy shape of Leif Ove Andsnes' interpretation and the equally alert, forward-moving playing of the London Philharmonic Orchestra under a kindred spirit, its principal conductor Edward Gardner.

If you ever doubted that Bizet’s Carmen, 150 years young next year, is one of the greatest operas of all time, this performance would have changed your mind. Among the four principals only Rihab Chaieb’s utterly convincing, consistent protagonist was the same as on first night 22 performances ago, and as ringleader we had the vivacious conductor of the second run, Anja Bihlmaier.

Not everyone knew what to expect from this fascinating programme. Rachmaninov’s Symphonic Dances, last of his orchestral masterpieces, is nothing like the more familiar aspects of his piano concertos. Nor is Busoni’s nominal attempt at the form, which seems more of a Symphony-Concerto than anything else, and style-wise impossible to pin down. Both works had the fullest care and focus last night.

Richard Strauss described conducting Wagner’s Tristan und Isolde for the first time as "the most wonderful day of my life". It’s understandable that Glyndebourne’s music director Robin Ticciati should wish to improve upon “wonderful” in conducting a concert staging in 2021 with "miraculous" in charge of the full Nikolaus Lehnhoff production. I challenge anyone to cite another Tristan more alert to every possibility – the electrifying, the ferocious, the transcendental.
