How did our nation's current opioid crisis come about? What steps were -- or were not -- taken as this epidemic was first being recognized? Who should ultimately be held accountable for this widespread tragedy? What policies enabled it, and who has benefitted most from those disastrous policies? On this edition of ST Medical Monday, we feature a "live onstage" interview that host John Schummann recently recorded here in Tulsa with Chris McGreal, a senior writer at The Guardian and former journalist for BBC.

Our guest today on ST is Jeffrey Zeigler, the well-regarded cellist who is known for his work with Philip Glass, Yo-Yo Ma, John Zorn, Kronos Quartet, Laurie Anderson, and others. A supremely gifted "crossover" musician whose work draws upon classical, jazz, pop, rock, folk, and a variety of other sources, Zeigler will soon perform here in Tulsa. His concert, presented by Choregus Productions, happens at the Tulsa PAC's Doenges Theater on Friday the 25th.

Our guest on StudioTulsa is Tamara Lebak, a Tulsa-based executive coach, organizational development consultant, and minister. She's also an accomplsihed singer-songwriter in the folk/roots/blues/alt-country manner, and she joins us to discuss her new album: "The Psalms Project: Volume 1." As Lebak has written of herself and her music online: "I'm a Universalist minister who believes that the Bible is ultimately about the relentless and persistent love of God.

We chat with Ian Shapiro, the Sterling Professor of Political Science and director of the MacMillan Center at Yale University. He's the co-author of a new book, "Responsible Parties: Saving Democracy from Itself," which he tells us about. The book engagingly explores why and how the form of government known as democracy has -- quite strangely and paradoxically -- reduced if not eradicated trust in political systems worldwide.

Our guest is Terrence Moore, a widely acclaimed photographer who's been shooting images along Route 66 for 40+ years. He tells us about his new book, "66 on 66," which gathers his finest images culled from the many hundreds he's made over the years of "the Mother Road." This book, with a corresponding text by local historian and author Michael Wallis, is just being published, and both Moore and Wallis will appear at a Magic City Books signing here in Tulsa on Friday the 18th. Details are posted here.
