Les demoiselles de la nuit (The Ladies of the Night) is in fact a ballet about cats, another French specialty (just ask Collette). The plot really doesn't matter: the music is indeed quite feline, quirky, and lots of fun, particularly in the extended Entrance of Agathe and the final Dance of the Rooftops. If the strings of the Ulster Orchestra have a couple of unsteady moments in this latter piece, it can only be because it must be very unfamiliar music, certainly not easy to play from an ensemble standpoint, and this quibble aside the performances have all of the ebullience and sparkle the music demands thanks to Thierry Fischer's confident guidance. Hyperion's terrific sonics will have you dancing on the rooftops too.
