Right from the start Estonian band BESTIA didn't tend to release a lot of material. From year to year new demos and promos appeared. They, as a matter of fact, contained the same songs but the sound quality and skills became better and better each time. Finally, the time came when all the songs, planned to be a part of the debut album, were shaped and the musicians could play them with closed eyes. This is where "Hallutsinatioon" appears. BESTIA plays good black/death metal. Riffs, characteristic to both styles of extreme music, are twisted in every track and you can hear symphonic keyboard insets in the background. Don't worry, there aren't too many keyboard insets; the keyboards aren't dominating in the music of this Estonian band. Nocturnal graveyard atmosphere is enforced with werewolf howling (Libahunt) and grave digging (Kolmas Haud Vasakult), not mentioning the only ambient track Ruunide Leidmine. I advice those, who are familiar with band's demos, to listen to the same songs but with new arrangement.
