Hi List members: I was listening yesterday a Cd By Reinhard Goebel and Musika Antiqua Koln that included a marvelous sonata by Vivaldi which is based on "La Folia". Some other composers have composed Variations on this "Leave", so my question is: What exactly is "La Folia de Espana"? What other composers have used? Any comments? Thanks in advance Arturo Llamas
