“Sauer’s technique is impeccable but never in evidence for its own sake. From the opening phrases, one feels a friendly warmth and welcoming lightness of spirit, punctuated by gruff cadences; all of this seems true to the composer and to the music. The pianist is engaged in an enlightened conversation with each individual listener. …These are experimental sonatas, in unconventional combinations of movements; Sauer, who obviously knows them well, seems to probe and find answers to reveal to us. … Sauer has a keen feeling for balance, both at the keyboard and interpretively.”
