Before releasing their now legendary debut LP, Piknik Caleidoscópico in 1986, Los Negativos recorded a four-song demo with the help of their own personal "George Martin," producer and sound engineer Enric Lindo. Recorded on four tracks, it displayed clear influences from psychedelia, garage rock, and '60s folk-rock: the Beatles, the Byrds, the Seeds -- not forgetting local bands like Los Salvajes. This early demo, released on cassette, introduced them to the underground scene of the time, even getting airplay on Radio 3's "Diario Pop" program. Now, for the first time on vinyl, you can enjoy these brilliant songs exactly as they were originally conceived.
