Two more contrasting pianists than Yuja Wang and Martin Helmchen would be hard to find. To move within 24 hours from the glittering assault of Wang’s technique to the restrained, almost introverted, Helmchen is an exercise in extremes, and one that left me yearning, Goldilocks-style, for a soloist neither too hot nor too cold, but just right. Dvořák’s Piano Concerto may have been a sober affair, but the London Philharmonic Orchestra and Vladimir Jurowski bid farewell to their Southbank season in a blaze of Central European passion and music by Suk and Janáček.

A mischievous part of me firmly believes that from the mountain of dubious art works produced in the world since the 1980s, the most dubious of all have been the percussion concertos. I know I’m being somewhat harsh, for I’ve thrilled along with most audiences to James MacMillan’s Veni, Veni, Emmanuel – far and away the best piece ever premiered by Evelyn Glennie, instigator of this percussion avalanche. But these ears have also been witness to enough trivial and meretricious concoctions to feel at least some trepidation before the launch of another percussion world premiere.

The onerous task of recording all 205 national anthems for playing at the Olympics medal ceremonies has fallen on the London Philharmonic Orchestra. An edited group of 36 players has recorded the anthems at the Abbey Road Studios in 60 gruelling recording hours over six days. But which would try their patience most?

Despite the best attempts of Stephen Johnson’s programme notes to create synthesis from last night’s London Philharmonic Orchestra concert, there was something rather smash and grab about the programming. It was as though Jurowski, suddenly inspired to play classical Supermarket Sweep, had emerged with a disparate trolley-load of Zemlinsky, Mozart and Szymanowski – oh, and the Brahms Violin Concerto.

Poor old Stephen Hough. The Liszt double. Again! Was he not at all Liszted out after last year's epic bicentenary? Were we not Liszted out by last year's epic bicentenary? Hough has been living, breathing and eating these two pieces for the past year and a half. The familiarity might have bred contempt. Amazingly it hasn't. In fact, all the prep work of last year appeared to make this performance of the first two piano concertos one of the most satisfying I've heard.

At last, a bag of sweets! In earlier concerts from Vladimir Jurowski’s LPO series Prokofiev: Man of the People? much time was spent  consuming the composer’s flat soufflés, experimental rock cakes, or the fancy dish that was really haddock. Interesting for the brain, maybe, but the diet on occasion has been hard on the stomach. Not that any of this impinged on audience numbers: the season has definitely proved Jurowski’s happy lock on the London Philharmonic’s audiences. They will follow their artistic guru and Principal Conductor almost anywhere.

The London Philharmonic’s current festival – Prokofiev: Man of the People? – is all about the question mark. While the festival’s concerts, lectures and even its classical club-night each make their own statement, the overarching spirit here is one of exploration, of questioning. Jurowski and his orchestra are peeling back the composer’s grinning modernist mask and attempting to expose the human face (or possibly faces) behind it.

How odd that Musorgsky, a composer sanctified beyond his very individual deserts for making social statements in his art, should be feted by an orchestra, or rather an orchestral management, which says music and politics don't mix.
