Adrienne Rich's poem "Diving Into the Wreck" uses the vivid metaphor of underwater investigation to say something personal and universal about uncovering and recovering an understanding of truth. Because April is National Poetry Month, host David Garland presents a recording of Rich reading her poem, and uses it as a starting point for a sequence of songs by Toby Twining, Panda Bear, Antony and the Johnsons, Joshua Stamper, and others, that also seem to address worlds underwater and the search for truth.
