Defektno Efektni has been played on NTS shows including Yesterday's News, with D first played on 11 March 2020. The band was formed by Urbana Gerila 13-year-old guitarist Slobodan Ne?ovi? "Loka", with the bassist Branko Petrovi? "Bane" and drummer Dejan Ignjatovi?. The band had only four songs written and two of them, "A" and "D" appeared on the Artisti?ka Radna Akcija compilation featuring the second generation of New Wave and punk rock bands in Belgrade. The reason why they gave the song titles with alphabet letters was because they did not like the names they came up for the tracks.
