The power of art to change people and communities can be breathtaking. This week we talk with Johann Zietsman who has orchestrated powerful art experiences internationally from South Africa to Mesa, Arizona. Johann is executive director of the Mesa Arts Center.

We also find out which cities are best prepared for $4 a gallon gas and which are not when we visit with Warren Karlenzig of Common Current. Warren is author of How Green Is Your City. Warren has worked with national governments, the State of California, major cities, and the world’s largest corporations developing policy and strategy for 20 years.

Smart City is a syndicated, weekly hour-long public radio talk show that takes an in-depth look at urban life: the people, places, ideas and trends that affect us all. Host Carol Coletta, president and CEO of CEOs for Cities, talks with national and international public policy experts, economists, business leaders, artists, developers, planners and others on the pulse of city life for a penetrating discussion on urban issues.

Smart City
is broadcast at 6 a.m. Saturday and Sundays on WKNO-FM, but it is also webcast and podcast. For the webcast, times for the broadcast in other cities and to sign up for the podcast, visit the website.

Note: We’ve received numerous emails asking about the change in the broadcast time of Smart City in Memphis. We’re extremely grateful to WKNO-FM for their instrumental role in making it possible to have this program in the first place and we will always remain so. In answer to emails, however, we did want to respond: If you would like the time moved to the later time that it previously had (as many of you have said), please contact the radio station program director.
