Ooooooh boy! *ducks from the bricks about to be thrown at thrashard*
I politely disagree, my good sir.
It was only their third singer change, and only their second long-time singer. Why change names then? And John was a great singer, even if the material they wrote when he was the singer wasn't the best. (After SOWN anyway, that was awesome.) And even then, nearly every album after that had many pretty good to awesome moments. It just wasn't thrash.
Don't get me wrong; I think Joey was awesome and it was pretty fucked up the way they canned him (OVER THE PHONE?! And they didn't even give it to him themselves! Pretty cowardly IMO), but ya know. Openmindedness=good.
