Thirty-five years ago, in March of 1977, in the heart of downtown, the Tulsa Performing Arts Center first opened its doors --- and Ella Fitzgerald, backed by the Tulsa Philharmonic, offered this beloved venue's debut performance. Built with a combination of public and private funds, following a 1973 bond issue, the Tulsa PAC is owned and operated by the City of Tulsa; it remains a leading arts/cultural/performance space for Tulsans of all ages and backgrounds. Our two guests today offer a host of anecdotes and asides as to what makes the PAC so special --- and so vital --- a part of our community. They also speak about how and why, with the remarkable rejuvenation of downtown Tulsa now in full gear, the PAC's best years are yet to come. We're pleased to welcome to StudioTulsa both Nancy Hermann, Director of Marketing for the Tulsa PAC, and Chad Oliverson, Marketing and PR Manager for the Tulsa PAC Trust. (To learn about the many and various upcoming events scheduled to occur at the Tulsa PAC, you can visit tulsapac.com.) Also on today's show, our commentator Mark Darrah offers a sharp and perceptive (if not necessarily "bulleted") critique of power-point demonstrations.
