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.

Mitsuko Uchida continues her world tour of Schubert sonatas with two concerts for the home crowd, this the second of her appearances at the Festival Hall. The tour coincides with Uchida’s 70th birthday, but the years have done little to diminish her technique.

When you've found your living ideal for Schubert's sonatas - Elisabeth Leonskaja, surely - it can be a challenge to stay open-minded and welcome another take on the profundities.

"Mitsuko Uchida plays Mozart" might have been the marketing tag to sell out this first concert in the Scottish Chamber Orchestra's 2017-18 season (despite student and free under-18s take-up, the Usher Hall still wasn't full). "Dvořák Symphony No.

Mitsuko Uchida specialises in elegant, if uncontroversial, interpretations of core Austro-German repertoire, yet she’s never predictable, and every performance is full of unexpected insights and welcome surprises.

Leonard Bernstein once said that his favourite piece of Stravinsky was whatever one he happened to be listening to. I have a similar feeling about Mozart piano concertos: I love them all in their turn, and last night I heard Mitsuko Uchida bring two of the greatest of them to life, as pianist and director, alongside the Mahler Chamber Orchestra.

The justification for playing Brahms with a chamber orchestra is well rehearsed. In fact, I have on my desk a Telarc boxed set of the four symphonies “in the style of the original Meiningen performances”, recorded by the Scottish Chamber Orchestra under the visionary Sir Charles Mackerras in 1997. Then, as now, the idea was to lighten the texture and give greater prominence to the woodwind. By drawing back the dense curtain of string sound, the light could shine through and Brahms’ contrapuntal delicacy be revealed.

After the broad, lyrical Shostakovich Tenth Symphony Andris Nelsons presented at the Proms last week, Vladimir Jurowski’s austere and unrelenting Eighth came as a shock. The two performances were equally fine, but at opposite ends of the Shostakovich spectrum. And the effect was intensified last night by a particularly terse programme, delivered with unrelenting intensity. No easy listening here, but plenty of raw emotion, and everything delivered with utter conviction and to the highest musical standards.

If you were one of the world’s most famous pianists, you’d surely want to explore the masterpieces among Lieder with the great singers. Having chosen less than wisely for Schubert, as some of us thought, Mitsuko Uchida has now found a powerful voice for Schumann, that of German soprano Dorothea Röschmann: opulent, many-hued, maybe a size too big for the fickle Wigmore Hall acoustics but always impressive.

While the Berlin Philharmonic's progress through London with Simon Rattle has grabbed the column inches away from the rest of the capital's classical music offerings this week, a delightful mostly Ravel programme from the Philharmonia should not be passed over.
