Great conductors, like efficient auto engines, apply a lot of torque – they can use a little energy to achieve great surges of movement. Now aged 91, the American-born Swedish maestro Herbert Blomstedt sometimes hardly seems to raise his baton-free hands. His feet, meanwhile, remain more or less immobile. Yet, like some highly-geared sports car, last night the Philharmonia zoomed, boomed or swerved at the merest distant kiss of his fingertips.

If Gilbert and Sullivan did the Bible it would sound a lot like Hubert Parry’s Judith. Premiered in 1888 and last heard in London a year later, the oratorio – whose principal claim to fame is as the original home of tearjerker hymn tune Repton, better known as “Dear Lord and Father of Mankind – has been lovingly restored to life by conductor William Vann and the English Song Festival, who will record it with Chandos later this year.

Mozart in E flat (the Overture to The Marriage of Figaro) and in G (the K.453 Piano Concerto), and Schubert in C – the “Great” C major Symphony, no less – ushered spring into the Festival Hall on a warm and sunny Sunday afternoon.

No successor has yet been named to Vladimir Jurowski as Principal Conductor of the London Philharmonic, so it is interesting to note that Edward Gardner is making several appearances with the orchestra this season. The two conductors are similar in their dynamic approach and brisk, efficient tempos.

Standing next to the warm brown beast of a piano built by Blüthner in Leipzig in 1867, Sir András Schiff advised his audience last night to clear their minds and ears of preconceptions. He told us that his rendering of Brahms’s first piano concerto – tonight, he will return to play the second – “should be like a first performance”. In reality, he added, that premiere (in 1859) turned out to be “a colossal failure”.

Feelings run high at the Hayward Gallery in a fascinating pairing of two artists from widely differing backgrounds. Kader Attia muses on unhappy, conflicted relationships between cultures in visual meditations on variations of colonialism. Diane Arbus, who died at the age Attia is now, photographed people who were often at the margins of society.

Just as our brief, premature spring collapsed into the bluster of Storm Freya, the Enlightenment certainties of Haydn’s more dependable cycle of nature blew into the Royal Festival Hall. Perhaps because its lovely but (for the most part) serene music tends to occupy the sunlit uplands, The Seasons has never quite secured the automatic respect accorded to the cosmic and human drama of its immediate forerunner, The Creation.

When a pianist directs from the keyboard, the result can be a sedate affair: a matter of minimalist time-keeping while the soloist shows his or her fancy moves. Not so with Dame Mitsuko Uchida and her long-term partners, the Mahler Chamber Orchestra. Clad in a sort of blue magician’s gown over severe black, Uchida – who has just turned 70 – stood to conduct, vigorously, the opening passages of last night’s two Mozart concertos at the Royal Festival Hall.

Pianists most often cite Radu Lupu alongside Martha Argerich and Grigory Sokolov as the greatest. So it was hardly surprising to see so many top musicians in a packed audience, buzzing with expectation for the 73-year-old Romanian's most recent UK appearance with a conductor he respects, Paavo Järvi. Lupu appeared at Steven Isserlis's 60th birthday event at the Wigmore towards the end of last year, but before that hasn't been seen here since 2014.

Harpers on the undeniably offensive aspect of Wagner the man might question attending a concert performance of his second Ring opera on World Holocaust Day. Fortunately there's nothing anti-semitic to be found anywhere in Die Walküre.
