WHAT: iHeartPodcasts and Kaleidoscope today premiered “On Musk,” a podcast hosted by Walter Isaacson, author of bestselling biography, Elon Musk. What is it like to shadow Elon Musk for two years? To sit courtside as he builds a rocket? Or tears apart an engineer? Or couch surfs at the homes of billionaires? And how on earth do you make sense of it all? Walter Isaacson is the biographer of giants: DaVinci, Franklin, Doudna, Jobs...and now Musk, former enfant terrible, rocket launcher, electric car innovator, and Twitter—er, X—disruptor, to put it gently. 

In this four-part series, author Evan Ratliff (“Mastermind,” “Longform” Podcast) sits down with Isaacson to draw out the behind-the-scenes stories of this epic biography, and what the writer has learned as an outsider inside Silicon Valley.
