Watch soap2day. Jazz Slave Ships was a site-specific performance collaboration between Vancouver artist Jan Wade and London-based performer Vanessa Richards that involved the creation of an ancestral altar. It took place in two U.K. ports in October 1996: on the West Coast in Whitehaven, Cumbria (the last English slaving port), in an 18th century bonded warehouse used to store liquor and guns used in the slave trade; and on the East Coast in Hull, Yorkshire in Wilberforce House, the birthplace of the anti-slavery pioneer William Wilberforce and now a museum of anti-slavery. The production took place over a 3-week period that began Sept. 30, 1996.
