“The Blood Quilt,” like another show now playing Off Broadway, Dominique Morisseau’s “Bad Kreyòl,” similarly buckles under the weight of an attempt to capture the totality of a cultural experience. Gullah Geechee sea island Blackness, Caribbean-American Blackness — these are experiences that deserve representation, but not necessarily in one fell swoop. And yet in an art form that already lacks for marginalized stories, theater is also a space where Blackness has historically been — and to some extent still is — flattened into a singular African-American experience. So is there space for more? Perhaps a series of Kwemera plays that are given adequate space to sprawl out. Or a more focused, finely drawn sketch of Kwemera life that, like Clementine’s stitches, are “so tight even wind can’t whisper its way through.” Either way, I welcome more quilts to the collection.
