Stephen Faulke made me a "working man's" guitar after Santos Hernandez and Barbero, from the days when the distinction between classical and flamenco guitars was less defined. In many ways it's a simple guitar, cypress back and sides, but it sounds and plays great. The question was what to play on it.
I started looking at the Guitar Method (Flamenco) by Rafael Marin, published in 1902. It seems to connect the southern-influenced pieces of Arcas with classical and genuine late 19th-century flamenco (as far as my limited knowledge can make out). In short, I find it a fascinating book. You can download it for free from my site, and read more of my thoughts about it, which will be expanded in due course.
There are no profound pieces, but for guitar historians it is full of interesting things. For instance, here is a Solea by Arcas, but not the long rambling one we might have become used to. This one is shorter, tighter, and fun to play. I'm trying to develop the rest-stroke, which I haven't really done for 25 years! But it will give you an idea of to tone of the repertoire in the book. And, of course, I play without nails...

More videos on my webpage linked above, including a pmi tremolo - different from both the "classical' and 'flamenco' tremolos of today - and also a nice Peteneras.
Thanks to Stephen Faulke for making such a great guitar!
