Valerie Tryon...is a Liszt specialist, but a virtuoso with a brain, and in the Chopin Ballades she takes the hardest route of all: she plays close to the score with as little license as possible...Since the Fourth Ballade has more variety, more sections of different character than the preceding three Ballades, the performer has more decisions to make about changes of gear...Tryon probably has a better feeling than anyone for these "changes of gear" so that the narrative is articulated as powerfully as it can be, and she goes for the final section like a bat out of hell.
