After the performance at the "Od glave do pete" (From Head to Heels) television show where the band performed the instrumental "Ulazak u harem", originally composed by Točak's teacher, Dragoljub "Jarak" Jaraković but rearranged by Točak, owing to positive reactions, they decided to record the track as their follow-up single. In April 1975, the band signed the Ljubljana ZKP RTLJ and released the single "Ulazak u harem" with the track "Epitaf" ("Epitaph") as the B-side. However, after being offered the contract by the Zagreb Suzy Records to release the single through their label, the band signed yet another contract, releasing "Ulazak u harem" with the song "Sto ptica" ("A Hundred Birds") as the B-side, which resulted in the two labels simultaneously releasing the same single. The release of the singles became the first major music controversy in the history of Yugoslav music. Eventually the band chose to remain with the ZKP RTLJ label and were offered to record their debut album for the label. The following month, the band went on a Bosnian and Croatian tour with Bijelo Dugme and the East German band Puhdys, and had several live appearances with the Hungarian band Sirius and Austrian band Gypsy Love, followed by them headlining the Zagreb BOOM Festival.
