At an age when most artists’ best work is behind them, Mr. Taylor continues to win public and critical acclaim for the vibrancy, relevance and power of his dances. He offers cogent observations on life’s complexities while tackling some of society’s thorniest issues. While he may propel his dancers through space for the sheer beauty of it, he more frequently uses them to illuminate such profound issues as war, piety, spirituality, sexuality, morality and mortality. If, as George Balanchine said, there are no mothers-in-law in ballet, there certainly are dysfunctional families, disillusioned idealists, imperfect religious leaders, angels and insects in Mr. Taylor’s dances.
