The Vassar College Madrigal Singers performed works by composer Bill McClelland at Dance Theater Workshop in Manhattan. The 16-member ensemble sang McClelland’s “The Ballad of Don and Dan,” crafted by Ian Frazier from “news items describing a bizarre murder in Montana in the mid-1980’s,” as well as musical adaptations of nature poems by Elizabeth Bishop ’34 and Richard Wilbur. Though the choir struggled with the “dry commentary” of “The Ballad of Don and Dan,” they “delivered an otherwise smooth performance.”     The New York Times
