Everything was with Gene Hoglan. In fact most of the drums and guitar were written from Eric Peterson. There was one song with the guy from Lamb of God.
The new CD is really good if you like the older more melodic type of testament. I have heard the entire album about 4-5 times now. It's really good for what it is. I tend to like the Gathering and Formation of Damnation a bit more as they are a bit more in your face aggressive and heavy. But I still like the new one a lot. It's almost like a combination of all of their albums in one.
