Their first album released in 1995 was a historic moment, being the second hip-hop album ever launched in Romania, and its success also brought them a contract with a record label. Just a year later it was followed by Nimic Normal and in 1997 they returned with Suta, a record named the best of its genre for that year.
Parazitii continue the series of premiers in Romanian music and in 1999 they were the first band that received a fee for writing a musical score for a movie - Nordrand. The same year marked the arrival in the band of the person that will change the face of Romanian scratching., FreakaDaDisk, former member of another rap group, Morometzii.
