No, they are the PURVEYORS of random, technical death metal.
Their tone is hollow, their "riffing" noodly and without purpose, and they even threw in a part of a Beethoven symphony into one of their songs, simply because he goes so well with gory topics.
They are one of the bands to be criticized for what they do. I do not have a "hatred" towards most bands, just a dislike. Necrophagist has earned the dubious honor of being one of the bands that I hate. Complete garbage.
If you really wish to experience modern technical death metal, I'd suggest Kronos instead. Nothing outstanding, but a much better sense of riffing and much less noodling.
