I can't find out that much about it on line except I think that Brian Ahern might have created it and there was a bunch of good stuff recorded in it including many Emmylou Harris (to whom he was married I guess) albums that I personally consider some of the best sounding albums I have. I am particularly fond of "Roses In The Snow" and "Cimarron" (among others).
Does anyone on here know more details about his equipment in the truck or session techniques? Whatever was done there sure sounds "right" to my ears.
