Good posts, my man! Honesty compels me to admit that some of the artists you listed were new to me -- just goes to show that there is always something to learn. I have heard of Vicente Gomez, but never heard his playing -- I'll try to remedy that soon. I am familiar with the Romeros, David Moreno, and Chet Atkins, but the others were new to me. Chet Atkins, although not known as an acoustic guitarist, has an eclectic group of recordings going back many years. One of the more relaxed and enjoyable recordings he did was with Mark Knopfler about 10 years ago. The two clearly had fun making the recording.
I had a chance to hear Andres Segovia in concert around 1957, not long before I discovered Charlie Byrd, and he was astounding. The other guitarist of comparable caliber, who I heard about 2 years ago in concert in Seattle, is Christopher Parkening. Parkening did a program dedicated to Andres Segovia, which included some wonderful anecdotes, rare personal photos, etc., of Segovia.
Parkening's parents own a home in Idaho on the Clearwater River, across the river from a friend of mine. I hope that during one of my visits to my friend in Idaho that I will have a chance to meet and talk with Parkening.
