“[a] stylish overview of some of the last century's most important works...Yoshimatu's wonderfully quixotic and exotic Fuzzy Bird Sonata is a gem in the repertory and there's a real sense of identification here between Mleczko and the music, suggesting that yet more is to come from this talented player.”
Gramophone Magazine, 2010
A winning collection of pieces interpreted with flair by the noted performer/pedagog. An unabashedly romantic artist as reflected by her lush and warm tone quality.
