I've had a really hard time nailing exactly how this band sound as they were not atypical of the H-8000 madness that was rife in the mid 90s. That's not to say that they didn't sound that way as they do have elements of that style (particularly those accented vocals which bring to my mind their brethren Kindred) but its a less extreme variation of it. The likes of Liar and Congress were maxed out metal and holy terror hardcore (particularly the latter), Spirit Of Youth had their influences too but mingled them closer within one another so that their sound was purely holistic, thus making their influences that much harder to trace, hence my difficulty.
Anyway, see what you think,
