Colorado

(Note: This show first aired back in February.) On this edition of our show, a discussion with Sue Klebold, whose 17-year-old son, Dylan, was of course one of the two teenage boys who committed suicide ­after their murderous attack on Colorado's Columbine High School in 1999. Klebold has a new book out about this incident -- and more to the point, about the behaviors that she did and did not see in her son in the months and years leading up to that terrible April day.

Our guest is the celebrated photographer David Halpern, who was based for many years here in Tulsa and now resides in Santa Fe. A wonderful exhibition of his work -- "The Essence of Place: Celebrating the Photography of David Halpern" -- will be on view at the Gilcrease Museum through the end of this year.

On this installment of our show, an interesting discussion with someone who's made a successful career of combining --- of all things --- music and geology. TU's Department of Geosciences has invited Dr. Jeffrey Nytch to appear at a few different on-campus events this week; Dr. Nytch, who will speak to music as well as geology students, is an assistant professor at the University of Colorado of Boulder, where he's also the director of that university's Entrepreneurship Center for Music. Thus he'll be speaking today (Wednesday the 5th) at noon at the University of Tulsa's Keplinger Hall.

Our guest is Ari Kelman, an Associate Professor of History at the University of California at Davis. Prof. Kelman discusses his interesting new book, "A Misplaced Massacre: Struggling Over the Memory of Sand Creek," which was published earlier this year by Harvard University Press. As we read of this volume at the Harvard U.
