In the early 1990s, Rambo was growing into an established performer. His third album "Psihološko propagandni komplet M-91" came out towards the end of 1991 at a time when breakup of former Yugoslavia was already in full swing. For obvious reasons, the least of which was the album's subtitle – "Psychological Propaganda Set", many songs contained heavy lyrics and a dark, militaristic atmosphere. In your face profanity and descriptive cursing was also par for the course, making this the first major music release in former Yugoslavia to take such narrative liberties. Tracks like "Smrt popa Mila Jovovića" (30-year-old poem by Božo Đuranović), "Jemo voli jem" (incorporating samples from Yugoslav aviators' anthem "Hej vojnici vazduhoplovci" as well as Šemsa Suljaković's "Izgubila sve sam bitke"), "Inspektor Nagib" and "Zdravo damo" became instant hits.
