Nicolae "DJ Swamp" Oncescu had been a full-time member of hip hop group R.A.C.L.A. for over a year when he decided to join B.U.G. Mafia after a few live appearances with them in 2002. Oncescu quit R.A.C.L.A. shortly after and became a full-time member of B.U.G. Mafia and a staff producer for Casa Productions. Tataee had stated in various interviews that he had been interested in adding a professional DJ to the group since the early 90s but the few hip hop DJs in Romania were already committed to other projects. Petre "Freakadadisk" Urda, who had collaborated with the group on their 1996 album, "Născut şi crescut în Pantelimon" (Born and raised in Pantelimon), had been a full-time member of Morometzii before joining Romanian hip hop pioneers Parazitii in 1998 and DJ Dox was also working with R.A.C.L.A. at the time. Oncescu parted ways with the group in 2008 citing creative differences and stated that he remained in good terms with them. However, group producer Tataee repeatedly mentioned that the break up had not been a friendly one and that he had not maintained any connection to DJ Swamp. Oncescu has since changed his professional name to Nicalai and has pursued a career as an electronic music artist, releasing his debut album "A.E.R. - Asta E Romania" (T.I.R. - This Is Romania) in 2009. In a 2011 interview, Oncescu claimed that the reason he parted ways with Mafia was a financial misunderstanding.
