In 1999, the band started working on a new studio album, for which Mihajlović and Stojanović decided that it should feature poly-rhythmic drums and scat singing. Nevertheless, Stojanović suggested that beside scat singing, several tracks should feature lyrics, which Mihajlović refused, and thus Stojanović made a decision not to play on the album. Mihajlović then hired Igor Malešević, at the time the member of Vasil Hadžimanov Band, but after not being satisfied with the rehearsals he was fired and Stojanović recorded the drums for all of the fourteen tracks on the album, which was entirely recorded in 72 hours. "Egregor", released by PGP RTS, produced by Mihajlović and Saša Habić, featured only one song with lyrics and on the rest Najdanović was featured on scat singing. The song "5. maj" ("May 5") was dedicated to Led Zeppelin and the theme "SOS" featured a sample of Josip Broz Tito's speech from 1948, older generation folk singers Vuka Šeherović and Mijat Mijatović, and an anonymous Radio Belgrade speak at the time of the World War II occupation of Yugoslavia. The album received mixed critics and did not receive an adequate promotion due to the NATO bombing of Yugoslavia during the same year.
