Please enjoy this preview of the first episode of Patt Morrison's latest miniseries, Smoglandia.  Smoglandia is a narrative audio series tracing the rise, impact and eventual retreat of L.A.’s most insidious form of pollution: smog. Through interviews with scientists, policymakers, filmmakers and artists who lived through the worst days, Smoglandia explores how Los Angeles became a testing ground for environmental regulation, and how science and innovation transformed public health. At a moment when our hard-triumphs over smog face new setbacks, Smoglandia explores a landmark victory for the City of Angels, and, through clearer air, looks forward to the lessons we still have to learn — and the battles we have yet to fight.

Producer's Pick: Kevin Demoff: The Man Who Brought the Rams (and SoFi) to LA

Even more than its sunny skies, rich history and Hollywood glamor, L.A. is defined by its people. In “Making Los Angeles,” from LA Times Studios, native Angeleno Glenn Gritzner sits down with the dreamers and big-thinkers shaping the city to explore how they got where they are. The result is a singularly intimate deep dive into the incredible lives of everyone from entrepreneurs, politicians and brand-builders to artists, activists and influencers. Glenn is a partner at a global public affairs firm and a registered lobbyist. He is well-connected within the business and political communities of Los Angeles. Behind every L.A. icon is a human story. Hear a new one every week on “Making Los Angeles.” The LA Times editorial staff was not involved in the production of this show.
