Wow, thanks for the compliments, guys.
@MondayMorningLunatic: I know about the rhythmic problems, I actually recorded that demo without a clicktrack, so the acoustic guitars are in and out of the click quite a bit.
As far as vocals go, I usually do some backing vocals and you can hear me on some if you have my band's album. I guess I am pretty self-conscious about my voice. My goal, really, is just to be able to sing well enough that I can create demos to provide to a seasoned vocalist and have it be good enough that they actually understand how I would like something to be sung. To that end, I think I usually am able to pull it off.
