In his twenties and just before Iran’s Islamic Revolution, Lachini had already achieved success in the world of pop music, creating music for the some of today's Persian pop icons as well as music for children. Most kinds of music were banned in Iran after the Revolution, so Lachini moved to France to study music and computers.

Living in Europe and studying at "Universite de Paris - Sorbonne" added a European flavor to Lachini’s music and influenced his style to become a distinctive and beautiful fusion of contemporary Persian and European styles. He also learned the technology to create exotic sampled Middle Eastern instruments, immediately putting him in a unique position when he entered the world of film music. The score for the Berlin Special Mention winner, Snake's Fang (1991), is an example of this. Variety comments: "...The exceptional music is a computerized version of traditional southern Iranian percussion. Soundtrack sets the pace and signals both danger and action throughout the film."

Fariborz Lachini has scored more than one hundred motion picture projects. He is recognized as one of the most innovative composing talents in the Middle-East and has scored for internationally-acclaimed Iranian filmmakers. One of his most recent works is Iraq's choice for Oscars 2006, Requiem of Snow. Variety wrote of the soundtrack: "...Fariborz Lachini's mournful acoustic music leaves a haunting aural residue in pic's wake."
