There’s no suggestion that Sergei Prokofiev suffered from bipolar disorder. Therefore, when he wrote his Piano Concerto no. 2 in G minor, dedicated to a friend who committed suicide, he was showing extraordinary empathy; the piece interleaves depths of abject despair with outbursts of furious violence and spells of fervent, passionate lyricism. The concerto doesn’t spare the pianist. It is so punishingly demanding, not least physically, that many of the greats haven’t touched it, while others hammer their way through the violent passages but are unable to put across the nuance.
Alexandre Kantorow, playing the concerto at La Grange au Lac in Évian, showed complete mastery of the work in all its ever-shifting moods. From the very first chords, the left hand rising and falling while the right plays a gentle, lyrical melody, Kantorow demonstrated the uncanny knack that every choice he made had the ring of truth, as if there was no possible other way that this music could have been played. Every change of dynamic felt just right, every rubato resolved so elegantly as to prompt a sigh of satisfaction. His demeanour was of intense concentration, bent from the waist until his face was at sniffing distance of the keys, the placement of his hands measured and deliberate on every chord, often seeming to caress the keyboard to conjure sound out of it.
The first truly punishing piano passage is the first movement cadenza (which lasts around five minutes, nearly half the length of the movement), in which Kantorow plumbed inner demons to their limits (of the composer? the pianist? the listener? we cannot know for sure). In the second movement Scherzo, the pianist is called upon to play at full tilt for two and a half minutes in a relentless rhythm that cannot be allowed to drift by the smallest fraction, punctuated by agonised shrieks from the orchestra. Kantorow delivered this without a blink. In the third movement, he moved brilliantly between threat and lyricism; in the fourth, the piano becomes insistent and then triumphant – or does it? Again, the question is left open.
