So this is how Bruckner's Fourth Symphony should go. It's taken a master conductor just past his 90th birthday and an orchestra on top form to teach me. No doubt Claudio Abbado and Brucknermeister Gunter Wand could have done so, too, but I never heard them live in this, the "Romantic", and they are no longer with us.

In a way, he was a second Bernstein.

The arc of Daniil Trifonov’s reputation has soared and then, to some ears, stalled in a familiar modern way. Russian Wunderkind pianist bags a sackful of competition trophies (Rubinstein, Tchaikovsky prizes; Gramophone Awards). Early recitals and recordings display stupendous technique allied to audacious, beyond-his-years interpretation. Hype shoots off the scale.

Imagine for a moment that you are at, say, the Derby. It’s pretty good. But then in flies Pegasus, the mythical winged horse. What happens?

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.

In the fourth performance of their UK tour, with Vassily Sinaisky replacing an indisposed Yuri Temirkanov, the St Petersburg Philharmonic gave a warm and rousing performance at Symphony Hall, Birmingham.
