As you will know I expect, Wales is one of the participating countries in this year's Smithsonian Folklife Festival. I have had the pleasure of interviewing the Smithsonian curator - Betty Belanus - about her research and the choice of the hundred people who will participate. You can hear the interview, and two of the performers who will be in Washington next month here. If you enjoy this, then think about subscribing to the weekly podcast versions of my two hour programme which always has an extensive "Welsh & Local" music segment, as well as news of Welsh artists.Smithsonian Festival site .
