In late 1983, Predrag Cvetičanin, with Zoran Đorđević, Branko and Boban, formed the band Dobri Isak. Having performed at minor local clubs, the band recorded a home made demo recording, however, the lineup dissolved during the Summer of the following year. After several months, Cvetičanin, with bassist Miloš Miladinović, and drummer Saša Marković "Markiz", reformed the band. In the period of 1984 and 1985, Nenad Cvetičanin, Predrag's brother, also became a member of the band. He joined the band while his own, Arnold Layne, was on hiatus. Together with Nenad Cvetičanin, the band recorded their first and only studio album Mi plačemo iza tamnih naočara, released in 1986 by the Niš Student Cultural Center, being the first release of the Studentkult production, which released an array of musical and literary releases. The album, released on compact cassette only and printed in a limited number of 100 copies, had been distributed by the Ljubljana ŠKUC, and rapidly sold out. The band presented their new material to the Niš audience, also performing at the 1985 Serbian Youth Festival in Knjaževac, winning the Best Performance Award, and gaining the opportunity to appear at the Dani Novih Omladinskih Novina in Split on Summer of the same year. After the Split performance, the band appeared with several other Niš bands at the Pozdrav iz Niša manifestation in Skopje. In a short period of time, the band had another performance in Skopje, appearing as guests at the first solo concert of the band Padot na Vizantija. During the late 1985, the band performed at the Rock Bands Festival held at the Belgrade Dom Omladine, and on early 1986, the band had two appearances at the Zagreb alternative rock festival Yu Rock Moment, on March in the semi-final, and on May at the festival finale, held at the Republic Square, performing with Let 3, Oktobar 1864, and Mizar. During 1986, Predrag Cvetičanin produced the recordings for the Niš New Romantic band Romantične Boje, even singing part of the lead vocalson the track "San", but the recordings were never released due to the unsuccessful negotiations with PGP-RTB. Dobri Isak performed until June 1986, when they held their last concert at the Niš Synagogue, appearing with Arnold Layne and Mizar, after which they decided to split up.
