The Blocked Heart is the fourth collection by the British poet Edwin Brock to be published in the United States. Reading his most recent verse, one becomes increasingly aware that the author's pervasive wry melancholy is not so much a passive response to the stress of urban life as a compassionate, virile outburst against it. Here we find, in many ways, a maturing synthesis of his earlier work: the candid, often bitter introspection of Invisibility Is the Art of Survival (1972 ), the more meditative, though no less incisive subtlety of The Portraits The Poses (1973), and the acerbic satire of Paroxisms (1974), a volume which includes illustrations by the poet's wife, Elizabeth. "[His is] the freshest voice from Britain in years," writes Hayden Carruth. ''Brock's sense of the formal tradition is indubitably English, but otherwise unpredictable, because he uses it very personally, amiably, and with great natural tact. His poems look to me like a breakthrough."
