I've listened to a lot of your songs man, most of which are worthy of being WWE intro themes, and this piece is no exception. It has that sort of dark, demonic kind of feel to it that suits even Kane himself, and just might work as a tag team intro.
The riff at the start is truly bad-ass ((always been a fan of high speed riffs)) and the middle compliments that start flawlessly. The ending is a bit softer - no, WAY softer than the rest, but hey, can't have it hardcore ALL the time, right?
Regardless of that, I give this track all my 5's, plus a bonus for such an amazing combination of riff, beat, drums, lead, bass, rhythm, melody, and overall enjoyment of the song itself. Truly a bad-ass and amazing track, man. If I joined the WWE on RAW, and had to choose an intro song, I'd say this would probably be it, along with a lot of your other songs. Hell, your work is so amazing overall, that I wouldn't know which song to pick, but this one would be really high up there on my list of possibilities.
Definitely a Top 10 pick, bro. Great work.
