"Butchered at Birth" was the 1991 Cannibal Corpse album that established their trademark death metal style, as their first album had more thrash elements to it. The vocals became noticeably lower and it was the first time their iconic "inhuman" grunting was heard.
Cannibal Corpse is a death metal band that formed in New York in 1988. They have had very little radio or television exposure throughout their career, although a cult following began to build during the releases of their earlier albums. The band's album art and lyrics draw heavily on horror fiction and horror films and are highly controversial. Over the years, several countries, such as Germany and Russia, have banned Cannibal Corpse from performing within their borders and have outlawed the sale and display of the band's original album covers. Yes, Cannibal Corpse's lyrics and artwork frequently feature transgressive and macabre imagery, including depictions of extreme violence and gore, however, the band has always defended this as an artistic expression that is clearly fictional. In an interview, they stated death metal is best understood "as art", and claim that far more violent art can be found at the Vatican, going on to point out that such depictions are arguably more transgressive because they actually happened. Amen to that.
