Cheveley Park Stakes
Russian Rhythm was foaled at Elizabeth Moran's Brushwood Stable near Malvern, Pennsylvania. She was sired by Kingmambo out of the mare Balistroika, making her a half-sister of the Royal Lodge Stakes winner Perfectperformance and a close relative of several top-class fillies such as Shadayid (1,000 Guineas) and Park Appeal (Cheveley Park Stakes).
