Chinese artist Xu Bing has several works currently on view as part of an exhibition at Mass MoCA in Massachusetts. Among the works are two 12-ton birds titled Phoenix that fill the museum’s football field-sized Building 5. Two years in the making, the birds were constructed from materials collected at various Chinese construction sites including demolition debris, steel beams, tools, and assorted remnants of migrant laborers. The male Phoenix titled Feng measures 90 feet long, and the female, Huang, is nearly 100 feet in length from beak to its steel tail feathers. More
