“M” is the most common sound in the word for “mother” in languages all over the world. In this stunning tribute to motherhood, contemporary dance, set to Pergolesi’s Stabat Mater, probes its joys and sorrows. Oshman’s dance explores the vulnerability and tenderness required of mothers, and the strength and ferocity that come with the territory. She borrows from the mythological mothers of history, including the Mary of Christianity, the dark and violent Hindu goddess Kali and the Four Matriarchs of the Old Testament: Sarah, Rebecca, Rachel and Leah.
