"À l’écoute de son disque (…), j’ai été séduite par des oeuvres (…), qu’il cisèle avec poésie et délicatesse. (…)
Qui a observé Constantin Sandu en train de jouer du Debussy, aura noté son toucher caressant, les doigts très à plat sur le clavier, comme pour combler le vœu de Claude de France : faire oublier que le piano a des marteaux. (…)
Même discernement, même délicatesse à l’œuvre dans la pédalisation de Constantin Sandu."

"Constantin Sandu impressed the public with the elegance of phrasing and his really velvety touch. The artist accomplishes the legato with a great delicacy. (...)His sound was gold plated.

"(...) this recital of Constantin Sandu (...) was both a revelation and an enormous musical delight. (...) Constantin Sandu goes through the amazing paths of Liszt's scores with the undisturbed attitude of someone who is walking along a smooth road and who, simultaneously, extracts all the poetical expression which they enclose.
