I don't know when Pogo jumped the shark - insofar as he warrants that phrase - but this Haydn recital was recorded when he was still the Fonz or thereabouts.
First, Pogo selects one masterpiece - the great A Flat sonata (46) - and a much earlier work which is damned inventive - number 19 in D Major. We are not bereft of great renditions of the former (look no further than Marc-André Hamelin, among others). It's no wonder Johann Sebastian Bach is often invoked when discussion turns to its miraculous slow movement where Haydn addresses God in a more formal language than usual. Its counterpart in the D major is likewise a treat: in its nostalgia, it bespeaks `morning-heroes'.
While his Mozart: Piano Sonatas K.283 & K.331; Fantasia K.397 is a stinker, i don't detect any mannerisms here from Pogo (neither work is over-characterized). A stupendous pianism in is play to the glory of the composer, not his mere prophet: one wonders anew at the genius of this man locked around in the fairytale castle in the middle of nowhere. Pogo's tone is in the Goldilocks Zone: it's just right (legato is used judiciously but not sparingly). The narrative is far from being episodic. Pogo clearly loves Haydn: his joy radiates forth in every note. His concentration is exemplary; for instance, he observes exposition repeats in slow movements, thereby stretching them beyond ten minutes: they'll leave you mesmerized . Such be Pogo's artistry, the question of whether these works should be played on a fortepiano arises not: they are.
One can only abominate DG for its cupidity: there's plenty of room on this disc for a third sonata. Do not buy this new. There are plenty of copies on the second-hand market. Like me, you'll be annoyed when this recital ends all too abruptly with constellations in close proximity.
