Windham Hill, for those who asked, is a recording label here in the U.S. which, (and I disagree with those who malign it,) features a variety of excellent artists. Most of them play little else besides their own compositions or at least mix in a goodly amount of them. Many of the artists have a "folky" sound to their music (whatever image that may conjure for you is probably fitting). Some of their recording artists include: Taj Mahal, Michael Hedges, Janis Ian, and George Winston. You can see what they have here.

As for DADGAD, I feel it is meeting the fate of so many other things which have met with the public attentions. It reminds me a bit of my mother's cooking. It was her habit to discover something "new", such as, "Hamburger Helper", and then use it in every way imaginable (and in some ways I would rather she had not imagined). She produced "Helper" meals until not only was the novelty worn off, but Dad and my brother and I were trying to find excuses to either eat out or at least visit some good friends close to meal time. Then, (at last!) Mom would make a new discovery - "Rice-A-Roni" or some such thing. Then the syndrome would begin all over again.

Many of us (perhaps, most) tend to "like" something until such time as it seems as if it is not only no longer novel, but has become downright common. Then, in order to excuse ourselves from continuing with it, we do a complete about-face and decide to despise it.

Frankly, (having lived through the "Campbell's Minestrone Soup" period, I totally understand.
