Although they weren't "major players" in the thrash scene (a little late in the fold) my two favorite thrash vocalists were Joel DuBay of Powermad and Brad Divens of Wrathchild America. Both bands were definitely thrash, but still melodic. I loved that combination. n honourable mention to Mike Howe as well. Metal Church's "Blessing in Disguise" sort of blurs the line between American Powermetal and thrash and he is a MONSTER of a vocalist.
