I like the ominous mood at the beginning and the echo-y vocals. The texture is a bit bare at times, but I'm enjoying the build-up into :41 and the gritty mid-range bass at the drop. Elements of the sound design and arrangement are a bit generic, but the vocal details ("oh"s and "hey"s) are nice, and the sample at 1:25 also fits in well. Overall, my favorite element of the piece is probably the production - it's crisp and well-balanced, but also not over-compressed or artificial-sounding. The atmosphere and vocals are also big pluses here. Strong work, Annihilate! ^_^
