\"Whether it was the blazing speed and facility displayed in the \"Touche Bloquees\" Etude, the eerily translucent sounds he produced for \"Cordes Vides,\" or the discordant chorus of bells he unleashed in \"L\'Escalier du Diable,\" Mr. Aimard\'s performance was a revelation. This last etude ends in complete sonic pandemonium. (The score includes eight fortes and the instruction for the pianist to play with all his might.) After the colossal final chord, the sound hung heavily in the air, like thick smoke after an explosion.\"
