The first three are the most common ones I hear, but as for the fourth one, I hear get Parkway sometimes, but I also get All That Remains, A Day To Remember, Bullet For My Valentine, Underoath, Trivium, Of Mice And Men, Bring Me The Horizon (for some reason, even though they started as a Deathcore band), The Devil Wears Prada, etc. I guess what I am trying to say is that it's easier to narrow it down to three since the fourth one is interchangeable to some people. I don't think many people will argue with KSE, ABR, and AILD though.
That can't be josh, Jake was the vocalist when messengers was released in 07 right? This show was from 07, and this dude looks a lot like Jake I think. Plus, the vocals were way to good for it to be Josh, not that I didn't like thrill seeker but compared to Jake he's a sucky vocalist.
