This is the darkest recording yet from M:40. Musically, Arvsynd, is a natural continuation from earlier records: Heaviness combined with d-beat madness, desperate outbursts and controlled eerie darkness. They haven't changed the weapons, but time has sharpened the knives. The lyrics are about political turn Sweden and the world has taken in recent years. The title Arvsynd (original sin) refers to the sin we inherited from earlier generations, and the dying planet filled with fascism and egoism we leave to our children. The bomb has fallen. War is already upon us.
