How can Watch Tower AND Spiral Architect both be 'original'? The latter is basically a clone of the former.
Watch Tower/Spiral Architect, part II
If it weren't for the abominable singing, a lot more people would be open to the greatness that was Watchtower, who were more chaotic, but perhaps a bit less technical than Spiral .. somehow. Either way you can't call them a copy when only a few bands ever even played in the same league/style.
