Light Music took command with just over two furlongs to run and held off the late bid of Make Fast to capture the Listed Celebration Stakes at Newbury Racecourse to win by a neck.
The daughter of Elusive Quality, who races as a homebred for Her Majesty The Queen, has now won two of her three career starts.
Light Music is out of the Danehill Dancer mare, Medley, winner of the Listed Japan Racing Association Sceptre Stakes, and hails from the female family of G1 winner Spillway.
Elusive Quality is the sire of 14 G1 winners lifetime, a group that includes Kentucky Derby winner Smarty Jones, Australian Champion Sepoy, and Breeders' Cup Classic winner Raven's Pass. The sire's top runners in 2015 include G2 Santa Ynez Stakes winner Seduire, and G3 winners Beauty Parlor and Eh Cumpari.
