Koloss is the next album from Meshuggah and personally i would say that while it is a good album it is not as good as their previous work. While i would say that i am a big Meshuggah fan i was slightly dis-appointed by this release as it didn't really offer anything new or any musical experimentation. It is heavy, probably their heaviest offering yet and if this had been released by any other band doing similar stuff i would be raving over it but I have come to expect more from these guys. Definately worth checking out and if you can get it cheaper then grab a bargain. Also the 'big case' with extra stuff is not worth the price, nothing of any special note on it.
