Water surged through this Prom from first spray to last drop. But there was nothing damp or diluted about Edward Gardner’s helmsmanship as he steered the London Philharmonic Orchestra through a succession of liquid rhapsodies: three from the early 20th century; one from 1993.

From the animatronic cat on the bar of the Garter Inn to the rowers’ crew who haul their craft across the stage and the military ranks of “Dig for Victory” cabbages arrayed in Ford’s garden, all the period flourishes that helped make Richard Jones’s Falstaff such an audience hit twice before at Glyndebourne look as spruce and smart as ever in this revival.

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.

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.

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.
