The band was formed in the early 1980s by Arturo Lanz, Gabriel Riaza, and Juan Carlos Sastre, who had all been members of El Aviador Dro y sus Obreros Especializados.

In 1981, the band released their first single, "Necrosis en la Poya", on the Tic Tac label, followed by their debut LP, Héroe del Trabajo / El Acero del Partido in 1982.

The band was active in the early-eighties international tape scene where they established a rhythmic, experimental electronic sound that foreshadowed the emergence of the powernoise subgenre by over a decade.

The band returned with 1997's Polyglophone, the following year, artists such as Coil and Chris and Cosey contributed reworkings of Esplendor Geométrico tracks to the remix album EN-CO-D-Esplendor.

In 2002, Compuesto de Hierro was released, while a double CD compilation, Anthology 1981–2003, hit the shops in 2005.
