21C Magazine
Description
Multiple Piercings for the Mind. A forum for vanguard criticism, literary journalism and trendsetting design, 21C will be the late-night reading of extreme thinkers everywhere - intellectual thrillseekers who savor the vertigo that comes from leaning too far over the edge of the cultural abyss.
