The band’s foundation dates back to the beginning of 1995, when Lazar (guitars) and Vlad (drums, vocals) started off working on few compositions which could be reckoned to the genre of black metal stylistically. Speaking about Rossomahaar as it’s been in the year 1995, one would easily say there wasn’t much place for originality… Those songs were issued in the shape of “Grotesque” demo later on, though. A fact worth mentioning: both musicians simultaneously played in Moscow’s dark metal act Stonehenge, which was considered top-priority then, and therefore Rossomahaar’s rehearsals took place quite rarely, to say the least. However; both came up with an idea of putting the songs they composed on tape Summer 1997, although personal and musical disagreements ruined the whole affair. Three tracks were recorded, but never issued anywhere. In spite of this, Lazar decided to push the band forward on his own, and recorded “Grotesque” in August 1997 alone. The recording turned out to be rather unconditional in terms of sound execution (all songs were recorded using IBM486 hard disk and regular soundcard at Lazar’s home kitchen) as well as of originality, but the path was trodden. Despite that “Grotesque” and all the other works by Rossomahaar almost don’t have anything in common sound-wise, this demo turned out as something which the actual band was born from. After the recording was over, Lazar no longer wanted to work on this project. Consequently; no activities for almost a year.And now we’ve come to a turning point… The year of 1998 witnessed Lazar making the acquaintance of Kai Mathias Stalhammar, with the latter being editor-in-chief of cult web-magazine, Vae Solis. Kai owned literally thousands of CDs and could define Rossomahaar’s potential much better than anyone else, and particularly Lazar. It was him who convinced Lazar of the importance of resurrecting Rossomahaar, and the latter began seeking those to complete the lineup. By the end of the year, it was comprised of Lazar - guitars, vocals, Ixxaander (Tales Of Darknord, Der Gerwelt) - guitars, Kniaz’ (Stonehenge) - bass, Sigizmund (Mental Home) - drums, as well as Herr Stalhammar as the one responsible for poetry, management and overall concept. The band began to work on new songs, which were later executed at CDM Records Studio, entitled “Imperium Tenebrarum” and put out by More Hate Productions, young Russian label. Music changed drastically! Based upon raw and brutal riffs and ultramelodiousness, it simultaneously absorbed a lot of styles of contemporary metal subculture. The beginning of 2003 has been marked by record of an album " Regnum Somni " in which collective completely refuses from keyboard and goes on courageous experiment with wind instruments. Upon termination of record of an album the group has been compelled to leave drummer Yanarrdakh ' an ohm and drummer Vlad there and then comes to group, with which summer of 2004 the group has written down last album " A Divinity For The Worthless ".
In summer 2006 ROSSOMAHAAR has recorded their new single entitled "Moscow - The Sanguine Reign of Terror". The single includes three tracks with a total length of 20 minutes. This release establishes the general sound and content of the upcoming album.
