This week, Annie and Elah share an episode from one of their favorite podcasts, the Australian Broadcasting Corporation’s Sum of All Parts. For years, Robert Schneider lived the indie rocker’s dream, producing landmark records and fronting his band, The Apples in Stereo. And then, he gave it all up...for number theory. Host Joel Werner tracks Robert’s transformation, from a transcendental encounter with an old tape machine, to the family temple of a mysterious long-dead mathematician, Ramanujan.
