This week in the magazine, Dan Chiasson reviews Linda Leavell's new biography of the modernist poet Marianne Moore, "Holding On Upside Down." Here Chiasson talks with Sasha Weiss and Giles Harvey about Moore's poetry and her mother, with whom Moore lived for most of her life, and who was intimately involved in the creation of her greatest poems. Also, Ian Crouch peeks behind George Lucas's curtain. Audio of Marianne Moore in this podcast is excerpted from the Poetry Center Digital Archive, which is made available under a Creative Commons license.
