After their first single, Necrosis en la poya (1981), Spanish industrial band Esplendor Geométrico released their first cassette that same year: EG-1. A cult band and pioneers of industrial music, they were one of the first cases of true independence in the history of Spanish music -- not only financially and organizationally, but also in terms of creative independence. These first works were self-produced and distributed by the band themselves, before the appearance of Spanish independent record labels in the early '80s. The first edition of EG-1 (300 copies only) quickly sold out in the international underground circuit of cassette labels that was emerging during those years. It was reissued on the same format by different labels such as Datenverarbeitung (Germany, 1982), Ortega y Cassette (Barcelona, 1985), EGK (Madrid, 1987), and Línea Alternativa (Madrid, 1989), and later on there would be two CD editions. Without a doubt, EG-1 is one of the fundamental works by Esplendor Geométrico, where they started to develop their unique style of industrial music which would be such a great influence on other artists afterwards. Tracks like "Muerte a escala industrial," "Destrozaron sus ovaries," and "Neuridrina" are regarded by their fans as some of the best recorded by the band. On this vinyl edition (limited to 700 copies), the music has been remastered from the original tapes for the first time, achieving the best sound possible.
