Okay, now, I have listened to the Marble songs and it is indeed different from ZH. It has its merits and one could criticize it, but IMO it's good because it isn't the expected. In addition, I'm listening to the Secular Trend songs now. Again, different. Can one really believe Erik has been part of all this music? Secular Trend, Marble, and Zero Hour (maybe others, too), Wow.
Okay, last thing. I'm positive it is not easy to write lyrics and vocal parts for what the other guys in ZH come up with musically, I mean you've heard what they have put out before. We are talking about guys that are musically as near to perfect as perfect can humanly be possible. I'm sure Erik only wishes to continue that endeavor of perfection on his vocal parts.
