Catchy tunes, dreamy lyricism: Prokofiev is at his most ingratiating in his scores for the film Lieutenant Kijé and the ballet Cinderella. The Piano Concerto No. 1 was his conservatory graduation thesis—bravura, young man’s music. The Fifth Concerto is the work of a master, built for a virtuoso. It’s a kaleidoscope of moods: whimsical, threatening, serene, neurotic, relaxed.
