Terraphobia started out more as a heavy metal band than what they've become. It's kind of strange reading the band Bio on their Angelfire (yes Anglefire) website. He says that Terraphobia broke up originally due to fighting with the bass player who wanted to play grunge, but really the original band wasn't that far removed from grunge, they were heavy metal with a slightly darker outlook. Product Of Your Mind was a good EP but it certainly wasn't very heavy, however it was also 29 years ago. It was after Terraphobia broke up that Mick got into the heavier stuff, then he got further into it with Mort.
I haven't listened to the whole album yet but the single above is a step forward from Evilution and Enemy Within. I think his vocals have gotten better, lyric writing maybe not so much, but the whole package in the one song definitely seems like a better effort that Evilution.
