I'll be honest about what I think of Cryptopsy. Last February, I had had moderate exposure to them (Voice of Unreason, a couple songs from Whisper Supremacy) and was looking forward to their opening for Dimmu Borgir. Well, at the concert they took about 45 minutes to set up, and everyone looked really serious: clearly they knew what they were doing, and my trust for the band was certainly high.
It would be difficult to overestimate my astonishment at what I heard. I was basically treated to an hour of indistinguishable noise in which it was impossible (at least with the acoustics of the auditorium) to hear even a minimal amount of melody. The drumming was earth-shattering, but it did not keep any of the songs from being complete abominations. Add to this the fact that the new vocalist sounds awful, and you could say that there are just about no redeeming features to the Cryptopsy experience, at least in my humble opinion - well, maybe except that they made Dimmu Borgir sound like the best band in the world, in comparison. I've heard quite a lot of bands that were worse - at least technically - opening for someone somewhere, but seeing Cryptopsy live was by far the most shockingly disappointing event I have ever witnessed at a concert. I felt literally insulted by them. Some people may vehemently disagree, but personall, the best recommendation I could give to anyone about this band is to avoid them at all cost.
