Alright then, another couple of contenders in the heavyweight category. Either could be considered the founding voice of progressive rock. Many argue whether it's King Crimson, or Genesis that is the grand-daddy of all prog bands. Personally, I'll give the nod to Genesis. I like Lake's post KC work better than KC itself. Both vocalists have a very distinct and unique sound and delivery, and have often been imitated, but never duplicated (as much as I love Fish and Marillion, how many people have thought "Is this Genesis" when hearing Fish-era Marillion for the first time?)
Gabriel it is for me.
