George Rochberg’s relationship with the past is not one of nostalgia; it is one of intimate, living familiarity. Partita-Variations, an energetic and exuberant work, makes unpredictable forays into realms of tragedy, innocence, mischief and heartfelt affection. Nach Bach, written for the harpsichordist Igor Kipnis, is a discourse between two composers active centuries apart, yet united in spirit and dramatic intent. A dark and deeply anguished work, Sonata-Fantasia demands the performer’s ultimate emotional, intellectual and technical powers. Volumes 1 (8.559631) and 2 (8.559632) are also available.
