Hello,
when I think of old school flamenco, I always think of El Agujetas because he is obviously a throw back to that old school flamenco, the real thing. I find he sounds best with Moraito accompanying since Moraito Chico himself is a bit of a purist, in the sense that he is all about compas as opposed to playing the most difficult and fastest runs possible. They make an awesome pair as in Dominique Abel's movie about Agujetas. Here is some footage I have never seen but it looks very promising!
