“Perhaps the most striking aspect of Gerstein's interpretation is his ability to make the piano writing sound much lighter and more transparent than usual...Instead of the conventional barnstorming bravura, Gerstein brings poetry, balletic grace and an infinitely wide range of timbres. Yet in no sense does the performance seem understated.” - BBC Music Magazine, March, 2015
