Query: Bringing out the hidden complexity of Haydn

The problem with Glenn Gould recordings is that you need two sets of the same works: one Glenn Gould set and one by some other pianist, so you can see how the REST of the world does it. Otherwise, you won't appreciate the surprises that Gould's quirky genius is bringing to the music.The Haydn Sonatas on these recordings bring out all the hidden complexity in a seemingly simple composer. To ears trained on the later Romantics, Haydn can seem a bit simplistic and rhythmically boring. Not so in the hands of Mr. Gould. The joy and sunlight are all here, coupled with Gould's fascinating staccato, interesting left hand and his ability to ferret out the secret melody hidden between the lines. Whenever I put on this CD, I discover Haydn again. This CD stays so fresh and new, I am always amazed.
