[Aired on Monday, March 5th.] On today's show, we look ahead to the exciting and far-reaching day-long symposium, "Different Shades of Red: Woody Guthrie and the Oklahoma Experience at 100," which will happen on Saturday the 10th at the University of Tulsa's Lorton Performance Center. Our guest is Brian Hosmer of TU's Department of History; he's serving as the committee chair for this symposium. As he tells our host Rich Fisher, this event --- intended for general rather than scholarly audiences, with a registration deadline of 3/8/12 --- is a collaborative effort that will feature three panels, with each panel featuring three speakers. The panels include A Culture of Protest, which examines the political and cultural environment that shaped Guthrie's views; Red Dirt Roots, which considers Guthrie's musical influences; and Echoes of Woody, which addresses Guthrie's legacy as related to the Dust Bowl and Depression-era Oklahoma. Various educational/outreach programs are planned this week for Tulsa-area schools, too --- along with a "Woody Guthrie Tribute" at the Oklahoma Jazz Hall of Fame, featuring the jazz composer and musical polymath David Amram, at 5pm on Sunday the 11th --- and then, of course, immediately after the TU symposium concludes on the 10th, there's an incredible concert set to occur at the Brady Theater in downtown Tulsa (with Arlo Guthrie, John Mellancamp, Jackson Browne, The Flaming Lips, Hanson, and many others on the bill)....
