There are encores and encores – most a friendly, minimal farewell gesture from the soloist; some a jolly, festive unwind after a particularly taxing piece. And then there’s the luxury free gift that Sir András Schiff bestowed on us during the second of two Barbican concerts with Iván Fischer and his Budapest Festival Orchestra.

"Revelatory":  it’s one of those words which is now completely devalued through having been carelessly dropped into a thousand press releases.

Second performances are even more valuable than premieres, composers say, when it comes to launching a piece into the world. Spare a thought, then, for Jan Ladislav Dussek, who has had to wait over two centuries for this prize to be awarded to his Mass in G – really, a Missa solemnis – of a scale to rival Beethoven’s example.

While the Proms were ringing out the old season, the Wigmore Hall ushered in the big celebration of 2020: the 250^th anniversary of Ludwig van Beethoven’s birth. The venue’s year-long festival (actually longer – the actual birthday is December ‘20) kicked off with a Beethoven weekend with more than just Beethoven in it.

Any festival would be proud and honoured to end with the great Elisabeth Leonskaja playing the last three Beethoven piano sonatas. Here the Everest was swiftly scaled as the tenth concert of a packed Wigmore Hall weekend.

Cellist Raphael Wallfisch thinks outside of the box. His concert repertoire spans the popular concerto choices – the Elgar, the Dvořák – but he doesn’t stop there, and makes a point of seeking out the lesser-known and the little-heard.

Among the greatest violin concertos in the repertoire, the Elgar is far too rarely performed. One of the reasons is its huge dramatic scale and almost hour-long duration – Sakari Oramo wisely programmed it here with Dvořák’s relatively modest Seventh Symphony, but this was still a long concert.

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.

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.
