Recorded over the course of 4 years during late-night, afterhours sessions at RCA's Studio @ Calle Carlos Maurrás in Madrid (one of Spain's best and bigger studio around that time), it was the result of the duo's interest in unorthodox sound-sources which they manipulated in a sort proto-sampling collage technique based on random tape-loops and best heard in their original percussive studies; their dreamy, surrealist-like lyrical passages or the sort of deep primeval atmospheres first conjured by Cluster or Kraftwerk in the early 70's.The studio as an instrument: pure sound alchemy at work. The Wah Wah edition is the first ever vinyl reissue of this legendary LP reproducing the original gimmick cover, with sound mastered from the original tapes by Eugenio Muñoz, and featuring an insert with photos and info. It is a strictly limited edition of 500 copies only.
