It runs from February 16 to March 2.As we like to do when our major festivals come around, we ask the folks who are responsible for bringing them to us to fill us in.And as he has been for the past few years, actually since he got the gig, Executive Director Chris Doss is in the Artichoke Café with me to tell us all about every headliner in the festival.It’s an interesting festival this year, with some new faces.
