The parents of a Norwegian girl suffering from colic - a condition in which an otherwise healthy baby cries or screams frequently and, for extended periods, without any discernible reason - have found a way to keep her from crying: by subjecting her to the sounds of the Norwegian black metal band Satyricon.

According to the couple, Bianca was crying from morning to night for 14 weeks straight - except when she heard Satyricon's music.

"We tried other [types of bands], something not as hard as Satyricon. But even Rammstein was rejected," Bianca's mother, 37-year-old Jeanette Orme, tells the Fredriksstad Blad newspaper.
