I've actually made the transition to being more of a APC fan than Tool; and I have seen both in concert. I saw APC in Frisco and Tool in Fresno. The Tool concert was not as good for simple reasons which I will explain in a bit. You see, you have to catch Maynard on a good day, I think.. Sometimes you will catch him going apeshit on stage, which I witnessed at the APC concert. He was very verbal, conversing with the crowd and all. Now when I saw Tool, he stood tucked away in the shadows of a corner. He did not reveal himself the entire time. All you ever saw of him was the red paint he put on his body. You could barely see an outline of him it was so dark on stage.
I'm looking forward to the new Tool album, but more so the next APC which is quite a distance away.
