[2] Formed in 1972 in Belgrade, Pop Mašina was one of the first Yugoslav bands to move the 1960s rhythm and blues towards a heavier rock sound.

[3] The band gained largeopularity with their live performances, which gave the members of the band, Robert Nemeček (bass guitar, vocals), Zoran Božinović (guitar, vocals) and Mihajlo "Bata" Popović (drums), an opportunity to record and release their debut album through the state-owned PGP-RTB record label.

[3] The album's main theme was a psychedelic experience; originally, the opening track should have been "Tražim put" ("I'm Searching for a Road"), allegorically describing narrator's attempts to find a drug dealer.

[5] In a 2011 interview, Nemeček stated that he wrote the original lyrics for the album after some notes he made while being under the influence of LSD.

[7] In 2000, the album was reissued on CD by Polish record label Wydawnictwo 21, in a limited number of 500 copies and featuring the songs from the band's first and second 7-inch single as bonus tracks.

[7] In 2007, to celebrate 35 years since the release of the album, Nemeček, in cooperation with Serbian label MCG records, released the CD Originalna Kiselina – 35 godina kasnije (Original Acid – 35 Years Later) in a limited number of 999 copies.
