Simone. All the others are solid but she’s definitely the best. In fact I could see her going to the end as a co lead vocalist if that was how this section of the game was set up, which it doesn’t seem to be.
I voted for Simone Simons as she has the most range musically here. Johan Hegg is a great and very consistent vocalist but he's been doing the same thing from the beginning without much change. Also, Amon Amarth is losing me musically lately.
My only experience with Greg Lake, or so I thought, was the song I posted. Had no idea he sang in King Crimson too. Decent vocalist, but wouldn't vote him.
As for Ray Alder, I'm in John-Arch-is-the-best-Crew, and Alder's vocals do nothing for me.
