EN MAS’ introduces performance art with a focus on the influence that Carnival and related masquerading traditions in and of the Caribbean and its diasporas have had on contemporary performance discourse and practice, in both the artistic and curatorial realms. Indeed, EN MAS’ takes into account performance practices that do not trace their genealogy to the European avant–gardes of the early twentieth–century but rather to the experiences of slavery and colonialism through the mid–nineteenth century, the independence struggles and civil rights movements of the mid–twentieth century and population migrations to and from the former colonial centers for most of the last century. EN MAS’ takes its title from a pun on “Mas’” (short for masquerade and synonymous with Carnival in the English-speaking Caribbean) and “mass” (as in the French colloquial “en masse,” meaning all together). Throughout the 2014-2015 Caribbean Carnival season, EN MAS’ tracked nine artists—John Beadle, Christophe Chassol, Charles Campbell, Nicolás Dumit Estévez, Marlon Griffith, Hew Locke, Lorraine O’Grady, Ebony G. Patterson, and Cauleen Smith—as they engaged, transformed, or critiqued historical and contemporary Caribbean performance practices from Carnival in Santiago de los Caballeros, Port of Spain, Fort-de-France, Kingston, London and Brooklyn, to Junkanoo in Nassau and the New Orleans second line—or in their own imaginary cartographies and invented performance traditions. The resulting newly commissioned works took place according to different modes of public address and audience engagement including semi-private rituals at the margin of the festival celebrations and street processions in the midst of the carnival revelry.
