Jaamil Olawale Kosoko begins this festival on Monday at Judson Memorial Church, a dance venue that for him raises questions about history, memory and space. Starting Thursday, the action moves to Danspace Project at St. Mark's Church, where the South African artist Nelisiwe Xaba presents an evening of solos addressing the complicated politics of her birthplace. On Friday, Abby Zbikowski and Gwen Welliver each contemplate the impact of what they call "kinetic imagination." And on Saturday, Melinda Ring revisits her 1999 work "Impossible Dance #2 (still life)" in two distinct ways.
