Silencer is a DSBM band from sweden, the singer is fucking possessed.
Here's a quote from a last.fm user
he just sounds like a sick parrot.
After the release of “Death - Pierce Me”, the vocalist, Nattramn, was institutionalized in Växjö Psychiatric Ward, where he currently resides. There are rumours that he escaped once and tried to murder schoolgirls with an axe, and that he has mutilated himself, but no one knows the truth. The only thing for real is that he makes drone-ambient-darkspace music now under the name of Diagnose: Lebensgefahr.
