Brazil's most celebrated contemporary dance company, Grupo Corpo, returns to BAM with its signature blend of Afro-Brazilian, ballet, modern, and urban influences. Inspired by the laws of magnetism and set to an electronic score warmed by the sounds of the ocarina and cuîca drum, Ímã samples the kinetic shimmy and bounce of the Lindy Hop. Awash in color and light, prismatic group dances give way to solos, pairs, and new groups, continuously repelling and attracting and lifting one another aloft. Based on Sea of Vigo, the 13th-century song cycle by Martin Codax, Sem Mim draws on stories of maidens weeping in the absence of their lovers and professing their sorrows to the sea. The dancers, dressed in tattooed unitards and propelled by the rhythmic score, play with the interchange of calm and fury, like the ebb and flow of ocean waves.
