Nota: The titles of tracks 1 to 4 of side  A didn´t exist in the 1986 edition.
Very interesting compilation that contains the first sonic experiences of a band that still has a little influence of their origins in Aviador Dro. On side A, nine unreleased tracks recorded in 1980 including the first demos tape where their famous track Moscu esta Helado was included, and on side B, the Necrosis en la poya single and a recording of their first live performance in Madrid.
