When I met Marc Andre Hamelin (he has recorded the most difficult woks of Alkan, Albeniz, and Godowsky) I asked him about the most difficult piece he had played. His answer was convincing: “It’s a tie between Reger’s variations on a theme by Bach and Scriabin’s late sonatas” he said.When I talked to Leslie Howard (he has recorded the complete works of Liszt) I asked him about the most difficult piece he had played. His answer was convincing: “Beethoven’s Hammerklavier by far” he said.Opinions??
only Ian Pace can be compared to him when it comes to a vast and demanding repertoire.
How can you seriously compare someone who plays virtually nothing but modern repertoire? Firstly, it's anyone's guess how accurately such music is performed. You can't judge it unless you know it intimately. Even then, they can get away with a hell of a lot more than somebody who plays a large repertoire of tonal music. Secondly, there are absolutely loads of specialists who play reams of modern repertoire. I'm not saying he necessarily isn't uniquely talented, but I don't know of any real evidence that would make him stand out from all the others- including Jonathan Powell.
The only recording by Pace that I own is the Finnissy Verdi Transcriptions etc. and I must confess that I find it a poor basis for a comparison with Leslie Howard. That said, although Howard's repertoire in Liszt is (obviously) phenomenal, I have not really read a lot of people praising his performances. It's more usual to read of their being insufficiently exciting.
