I was in a podcast discussion about prog death metal last night, and despite being highly impressed with Cynic's comeback album, Traced in Air, I realized I never dug into their albums after that.
The next album Kindly Bent to Free Us, is actually great. There's some happy-sounding stuff, which I personally find jarring in metal, but tracks like Moon Heart Sun Head
have that Cynic prog magic. I think the death metal vocals are completely gone at this point, but the riffs and beats have a feel that you can trace all the way back to Human.
