From Barcelona, LOS NEGATIVOS stood out within the 1980s sixties-revival scene thanks to their carefully crafted look, lyrics, and thrilling songs. With their first album, "Piknik Caleidoscópico", originally released in 1986, they masterfully combined pop, psychedelia, garage, beat, and folk-rock, creating a distinctive lysergic universe that continues to captivate 40 years after its release. This 40th-anniversary reissue of "Piknik Caleidoscópico" preserves the album's original artwork but, for the first time, includes the black-and-white back cover, which is how the band originally designed it. In addition, the audio has been remastered again by the album's original producer, Enric Lindo, together with the members of Los Negativos. It also includes an 8-page trilingual booklet (Spanish, Catalan, and English) with informative notes by journalist and band's official biographer lex Oró, plus rare photos/memorabilia and a reproduction of the original lyrics insert.
