"Andrei Diev gave a dazzling recital of works, ranging from neglected sonatas by Soler to dances by Schubert, from Prokofiev to Messiaen. Mr. Diev has a wide interpretive range. He knows how to give Prokofiev's Sixth its acerbic edge and its contrasting melodic warmth, as well. Liszt's arrangements of Schubert were perfectly poised and wonderfully buoyant. Enthralling throughout."
The Chronicle (England):
"Mr. Diev's brilliance could only be marveled at. He is one of the best in the world."
"Andrei Diev is a pianist of great magnitude. His talent is the embodiment of the transcendental potential of art. His remarkable technique is aimed at revealing the secret of music."
"He plays, transformed by that which opens up to him beyond the boundaries of the notes, clearly revealing to us this secret without the least bit of falseness or demagoguery. He merges with the soul of the music and with the soul of the composer. Andrei Diev is a great pianist."
La Stampa (Italy):
"The solo part was played by an extraordinary interpreter, Andrei Diev, who demonstrated a magnificent technique and admirable musicality. Diev presented a marvelous reading; powerful and expressive, energetic and elegant, complete with a wonderful sensitivity to the breath of the musical phrase."
