Greg Stephens said it quite well, as did Dick Greenhaus.

There are very few places where one can go...especially in the USA... and hear mostly traditional music. To me, a perfect club would aim toward traditional, yet allow & encourage 'some' new stuff that is clearly based on trad or uses similar tune style, themes and instrumentation.
There are many, many places where 'newer', vaguely folkish music is done, and that is fine.... it suits the majority. But some of us in the majority love the idea of one little oasis where we can soak in tradition when we have a mind to.
