Lost in a morass of legal infighting for the last few decades(!), these films are required viewing for anyone with a passion for film. EL TOPO is best described as a "psychedeic frijole western" while THE HOLY MOUNTAIN is a "cinematic mindf*ck". These two films along with his FANDO & LIS (coming back into print) and SANTA SANGRE are all ground-breaking.
EL TOPO, THE HOLY MOUNTAIN, and FANDO & LIS are now available for pre-order. Allow me to recommend DiabolikDVD for your source:
