Matthew Zapruder, poetry editor for the New York Times Magazine and author of four award-winning poetry collections, enters the GrottoPod this week to discuss his latest work -- a book of prose due out this summer called Why Poetry? -- and the challenges and rewards of teaching poetry. Zapruder examines a life of poetry and muses on the role The Grotto has played in his life and career, the path that led him from a U.C. Berkeley PhD. program in Slavic languages and literature to a poetry M.F.A. He wraps up his visit by setting a tattoo date with Bridget.
