Korni Grupa was one of the first Serbian rock bands to achieve major mainstream popularity. Formed in 1968 by former Indexi keyboardist Kornelije Kovač, the band recorded many commercial pop songs released on 7-inch singles, with which they achieved huge popularity and appeared on pop music festivals throughout Yugoslavia. Already influenced by progressive rock, the band moved towards progressive sound with the arrival of vocalist Dado Topić, continuing, however, to release commercial singles. Korni Grupa's 1971 debut album "Korni Grupa" was the first long play album by a rock act coming from Serbia, and the fourth long play album by a Yugoslav rock act. The band's second, symphonic rock-oriented album, "Not an Ordinary Life", released under the name Kornelyans in 1974, was one of the first Yugoslav albums released through a foreign record label. Despite the success with the singles they released in Yugoslavia, the band disbanded due to the little success of "Not an Ordinary Life" and the song "Moja generacija", with which the band represented Yugoslavia at the 1974 Eurovision Song Contest.
