Their appearance on the Yugoslav musical scene in early 1970s was "equal to the appearance of flying saucers with Martians". They jumped on onto the dull musical scene, which tried to keep up with the world trend of sympho-rock, full of self-confidence and fresh ideas, and offered pure humor, sometimes on the verge of lunacy, instead of prevailing pathos and overlong solo sections. Frank Zappa was admittedly one of the band's models, and was often subject to comparisons with Buldožer's style.
They were also ignored by the media, but they successfully built the image of freaks on numerous gigs. Although they introduced themselves as "typical folk-pop ensemble from Slovenia", Marko Brecelj, one of band's frontmen, was often making unpredictable excesses like appearing on the scene in a wheelchair, burning his hair and beard, and holding long tirades loaded with cynism and irony. Despite everything, he received the award "Seven Secretaries of SKOJ" in 1976 for his solo-album Cocktail.
Such a thorn in the eye to the establishment could not pass lightly though, and some lyrics were censored during recording of the second album. Among other things, they were asked to change the word "nirvana" into "kafana". The record Zabranjeno plakatirati (No placateering) was on ice for a year, until Helidon from Ljubljana hopped in and issued it. The songs Ne brini mama, Helga and Dobro jutro madam Jovanović. By a mysterious chain of events, the band also received the Golden Arena award on the Pula Film Festival for the soundtrack for film Živi bili pa videli in 1979. In the meantime, the rhythm section changed, so the bassist Vili Bertok and drummer Tone Dimnik participated in studio sessions.
The same year, Brecelj left the band wishing to make a solo-career, and Bele took over the frontmanship. He proved he should not be taken lightly, and continued the Brecelj's style of excesses and provocation. The double live album Ako ste slobodni večeras (If You're Available Tonight) featured the kidding of all kinds. Intermezzos between songs were filled by made-up interviews of Antun Vrdoljak with the "public" on the topics of Buldožer's favorite themes—sex, drugs and Goran Bregović. The album contained covers of Roll Over Beethoven, renamed to Ko jebe Buldožer (Fuck the Buldožer), and verses from Pink Floyd's "Another Brick in the Wall" were sung to the melody of Oj, svijetla majska zoro. Arguably the greatest excess on the record, though, was Bele's longish obituary to Džoni Štulić, who supposedly burned himself as sign of protest for the Poland crisis.
Bele took over the position of chief music editor of Helidon label and managed to purchase the copyrights of their debut from PGP RTB, so the reissue came up in 1981. The band's activity slowly diminished in mid-1980s, after the poor album "Nevino srce". They never officially broke up though, and their "come-back" album "Noć" was released more than 10 years later, in 1995. Regathering of the band for an Ex-Yugoslavian tour is announced for the second half of 2006.
