Well, a change of genres for once. Discovered this not too long ago but when I did, it literally blew my mind away. I'm not really into Death Metal at all (aside from Death, Vital Remains and Necrophagist) but this is just awesome. One of the best death metal I've ever heard.

Only for Death Metal fans I think, or not, I don't know, I like it a lot.
