I have just ordered this CD so cannot comment on it. However, I do own a number of Haydn sonatas recordings (too many to go into - they've been my favourite for over 25 years.) Simply have to say that the previous reviewer is way off beam. The Gould recordings are (to quote Andras Schiff) "perverse" and someone who thinks otherwise has a screw loose. This isn't about only subjective taste (if you like them you like them) but in comparison with modern grand exponents such as (Alfred the Great) Brendel, Schiff, Reisenberg, Cohen, Ax, Richter, and Horowitz and fortepianists such as Schornsheim, Brautigam, Odiaga, Badura-Skoda, Staier, Hoogland, van Oort, Fukuda, Dütschler, Kojima and Ranki (as well as notable others such as Koscis, McCabe, Jando, and Kalish) the playing of Gould is nothing short of ridiculous. A parody of Haydn. Doesn't mean the previous reviewer is wrong about Planes but he sure is about Gould. Steer clear unless, like me, you have Haydn sonatas by all the others first.
