On this edition of our show, we listen back to our special conversation from early June with the highly regarded photographer David Halpern, who was for many years based in Tulsa and now resides in Santa Fe. "The Essence of Place: Celebrating the Photography of David Halpern" will be on view at the Gilcrease Museum through the end of 2017. (Note that you can access a free, on-demand audio-stream of our conversation here.)
