Jamie - watched your vids. Good shit man. You definitely have the voice required, and the look to go with it. I scouted around on youtube and found a few other vocal auditions and from what I have seen you shit on the rest. One dude had a great voice, but didnt really suit tech-death type music, and also he looked like a tool and used a TV remote as his mic
for a band like this (or most bands really), its not all about the sound. There are other factors that weigh in hugely as well. For example, Slash got the job of lead guitarist with Poison (prior to Guns) but they knocked him back/he knocked them back (bit of a mutual decision) because he wouldnt wear makeup and spandex. Image counts for alot, and you certainly have that.
Maelstrom - nice drumming (not that Im a drummer, or really even have much of a clue at all about it) but just personally, I would have rather seen you smashing on real drums. The electric kits visually seem (to me at least) like you dont require as much effort, therefore it appears like you arent really trying, or dont have a great deal of enthusiasm. Like I say, Im no expert, and from what I can tell you did a great job.
Good luck to both of you. how sweet would it be if you both got the jobs? Long shot I know, but there's always hope.
