Robert Caro: "On Power"
I am WELL aware that this isn't a podcast, though I'm including it here because (1) it IS an audio recording (get ready: Robert Caro HIMSELF reads it), and (2) his writing and his mind are exceptionally brilliant. In my eyes, there is no better living biographer or historian -- to read him is to read the most compelling history of 20th century America. (And a very BIG also: going to see him talk at the New Yorker Festival this week, which is exCITING to me.)
