Since I made a negative comment above, I actually watched the videos to get a better feel for them. Still far from my thing, but not nearly as bad as the first. I wouldn't call any guitar work that I heard particularly special, but definitely more substantial than what year hear in most rock music today. However, like I said, post-grunge hard rock and metalcore is not my thing at all. The only thing that I've ever really been able to get into is Shadows Fall's The War Within CD, and that really almost leans more toward the thrashy side of things with hardcore vocal stylings. The sound and lyrical style of most of this kind of music just doesn't do it for me. I can't really speak for how DH relates/compares to the other bands mentioned, since I'm not familiar enough with any of them.
