I listen regularly to a few podcasts–This American Life (for many years), The History of Rome, New York Times Book Review are regulars. Some I’ve dropped from the rotation, like New Yorker: Out Loud (now I listen only to those that grab my attention) and The Ethicist (you love or you loathe Randy Cohen. I loathe.) Last fall I discovered Radiolab, produced by WNYC. It’s terrific. The shows are well-researched, well-reported, varied, interesting, engaging, funny, emotionally draining–and Radiolab’s tightly-edited multi-voiced opening montage is like a 7-second roller-coaster ride. After listening to a few episodes I downloaded most of the show’s back catalog, which provided my commuting and workout soundtrack for weeks. I caught up on prior seasons and now feel empty–new episodes do not come often enough. Finding Emilie is a gripping narrative, intellectually challenging, and emotionally profound. If you like it, you’ll like Radiolab.
