“To play all these works in one session is a formidable undertaking and Fierro met the challenge with massive authority and assurance. His technique was at all times unimpeachable; the most difficult demands were mastered effortlessly. He stirred up immense storms of sound and was equally successful in realizing the most evanescent tonal effects. It was a strikingly impressive exhibition of piano playing as well as of musical comprehension.”
