POP MAŠINA was formed in Beograd, in 1972 by Robert Nemeček (bass guitar, vocals), Zoran Božinović (guitar, vocals), Ratislav Đelmaš (drums), and Sava Bojić (guitar, vocals). Sava Bojić soon left the band, and during the same year Ratislav Đelmaš left Pop Mašina and joined YU grupa. He was replaced by Mihajlo "Bata" Popović. Pop Mašina was one of the first bands on the former Yugoslav rock scene that moved from the 1960s rhythm and blues towards harder sound. They often organized free concerts, and in 1972 they organized a big free, open air concert at Hajdučka česma. The concert also featured bands "S vremena na vreme", "Porodična manufaktura crnog hleba", and others. In May 1973 they organized another free concert at Hajdučka česma, which featured bands "Jutro", "Grupa 220", "Med", "Vlada i Bajka", and others. In 1973 the band released their debut album "Kiselina". The album featured hard rock sound, but also featured psychedelic and acid rock elements. The album also featured several acoustic songs composed by Nemeček. "Kiselina" featured Sloba Marković on keyboards, and three songs featured Miša Aleksić (at the time member of SOS). The album also featured "S vremena na vreme" members Ljuba Ninković and Vojislav Đukić, Drago Mlinarec, and DAG members on backing vocals. After "Kiselina" was released Pop Mašina held a large number of concerts. These concerts were organized with the help of (at the time) journalism student Aleksandar Tijanić, and other Yugoslav progressive rock bands were often invited to perform. Pop Mašina had an attractive live appearance: Božinović was one of the first former Yugoslav guitarists that played long guitar solos, played guitar with a bow and behind his back. At the beginning of 1975, in Akademik Studio in Ljubljana, the band recorded their second studio album "Na izvoru svetlosti". The album was produced by Ivo Umek and Robert Nemeček. It featured Ljuba Ninković and Sloba Marković as guest musicians. The album featured live blues track "Negde daleko" recorded on a concert in Belgrade Sports Hall on January 2, 1974, and the song "Rekvijem za prijatelja", with lyrics written by Ljuba Ninković, dedicated to Predrag Jovičić, the former singer of the band "San", who died from an electric shock on a concert. The album also featured a new version of the song "Zemlja svetlosti", previously released on a 7" single. After the album release the band was joined by the keyboardist Oliver Mandić. However, he left the band after only several performances. In 1976 the band released the live album "Put ka Suncu", becoming the first former Yugoslav band to release a live album. At the end of 1976 Robert Nemeček left the band due to his army obligations, and the bass guitarist Dušan Petrović, the drummer Dušan Đukić, and the guitarist Vidoja "Džindžer" Božinović (Zoran Božinović's brother) joined the band. After he returned from the army, Nemeček moved to London, where he started working in the music instruments company Toma & Co. From London he also wrote for Yugoslav magazines RTV revija and YU video. The new Pop Mašina lineup moved towards jazz rock. The band recorded the single with the songs "Moja pesma" and "Uspomena". In 1977, Petrović left the band and joined Generacija 5, and was replaced by Miroslav "Cvele" Cvetković. This lineup announced the recording of the new album. However, in 1978, Pop Mašina disbanded.
