You brought up Cedric Zavala. I must admit I do not know much about Mars Volta, except that their live show has gotten TERRIBLE reviews. I know there is a massive difference between a great signer and a great frontman, and until the reviews of his live show changes, I couldn't endorse him on a list like this.
Cedric Zavala was great live with At The Drive-in he had so much energy on stage and sounded great live and really put on a show by himself, but now with The Mars Volta live they just have too many instruments going at one time that its ridiculous, back when they made more simple music their live shows were alot better and sounded good as seen in the concert videos Ive posted here and on their live CD Scab Dates
