Fazil Say’s interpretive daring and seemingly limitless imagination reap great rewards in the fertile territory of Debussy’s evocative First Book of Preludes and the mystical eccentricity of Satie’s best-known miniatures. Perhaps because their piano music was so different, Satie and Debussy were close friends. Whereas Satie’s titles look back to ancient Greek civilization, Debussy derived the inspiration for the individual preludes in his first collection from more contemporary literature, art, or nature.
