50th anniversary reissue, limited to 500 copies on black vinyl. Debut from the experimental folk/rock band from the revolutionary years of the late '60s in Chile. Remastered from the original pressing and authorized by the founding members, this edition also has the original artwork and unreleased material updated by designer Antonio Larrea. There is a handwritten data on the cover of the long play that one of the members of Los Blops has treasured for half a century: "1st record. Stgo - Chile. August 26, 1970", noted there on that day by Juan Pablo Orrego's father. In some sense it is a spontaneous birth certificate, not the starting point (Los Blops were already formed in 1964 in Santiago de Chile), but still somehow the beginning of the major chapters in their history. That LP, called Blops, is the first of the three that they recorded between 1970 and 1973 and made the band a primary reference for rock and popular song in Chile.
