Re-release in jewel case. Modulo 1000 is one of Brazil's famous progressive-psych rock bands of the early 1970s. Their only album (from 1972) became legendary in the collectors scene as one of the best South American records of all times besides Laghonia, Emiliano Zapata, Traffic Sound or Opus Alfa. As Luiz Simas (organ) remembers: "The music of Modulo 1000 had its own appeal to an audience that wanted a heavy, raw, experimental, psychedelic sound. Our kind of music did not make it to the radio stations. It was too wild. The distribution of the record was done in a very limited way. The record label directors, which probably didn't understand or even didn't like our music, did zero promotion for it."
