The hard parts are nice and clean, but it isn't a very exciting interpretation, is it? It never feels like it's on the edge or in danger of being out of control; I think it should. All the passages seem very disparate, one vignette and then onto another, rather than a cohesive strategy to develop drama. I liked the choice to play some of the segments more slowly, but it seems like a performance without a climax, when this piece should have several. I would also experiment with more extreme ranges of touch to try to bring in a more exotic sound in a couple passages; it is a showpiece, after all.
Listen to the performances by Entremont, (G) Ginzburg, and Canino.
