In December 1971, the lineup was completed with the arrival of Miša Nikolić on organ. Still largely a cover band at this point, the group played youth dance halls with covers of Santana, Deep Purple, Led Zeppelin, The Rolling Stones, and Jimi Hendrix. Soon after, the members decided to change the band's name. Influenced by "Smak sveta" ("The End of the World"), a "Hair"-inspired musical being prepared locally at the Kragujevac Theatre in dedication to the schoolchildren killed during the Kragujevac massacre, they agreed on Smak ("Endtime") as their new name while the play eventually never got staged. New name Smak occasionally got referred to in jest as S.M.A.K., a supposed acronym for "Samostalni Muzički Ansambl Kragujevac" ("Independent Musical Ensemble Kragujevac"). During this period, the band members spent time writing their own material, including 22 instrumental songs — from "Biska 2" to "Biska 23", written by Mihailović as a dedication to his friend Predrag "Biska" Albić (who was 22 at the time), featuring the defined band's sound as a combination of progressive rock with jazz and blues influences.
