The cover art for this album should give you some indication of what you may find inside; two hooded chinese warriors with machine guns are are not likely to be found on the cover of a pop or R&B album. Rest assured, this is not easy to listen to, in any way.
It is, however, a masterpiece.
Doom metal typically consists of heavy low end bass and guitars, and big albeit pretty simple drumming, combined with occasional growling vocals. It is usually excellent, but rarely varied. The Body take this template and augment it with choral choirs, Steve Reich-like vocal looping, and singing that sounds like someone being ripped apart. It is genuinely disconcerting, and at times terrifying.
This is a violent and claustrophobic album, and is one of the most innovative doom metal records I heard in a long time.
