Dredg - Catch Without Arms
This is an incredible album. I went to a Coheed and Cambria concert and heard them playing before Coheed. They are incredible live and the album is awesome.
Coheed and Cambria - Good Apollo, I'm Burning Star IV, Volume One: From Fear Through The Eyes of Madness
This album is one of the best albums I've ever heard. The album before this one: "In Keeping Secrets Of Silent Earth: 3" is also incredible. These guys are great live too.
The Used - self titled
My Chemical Romance - Three Cheers For Sweet Revenge
The Killers - Hot Fuss (was 2004)
Our Lady Peace - Healthy In Paranoid Times
Fall Out Boy - From Under The Cork Tree
I could go on. There are tons of good stuff coming out all the time. Sometimes you have to look for it though.
