Yeah, Sigh's drummer is not as intense as others.
I take it your favorite genre is Metalcore, I am seeing a pattern here. :P
The song is nice, I have heard August Burns Red before. I haven't seen Greiner being mentioned ever as the greatest Metal drummer in any name-dropping lists of greatest Metal drummers in the decades I've been listening to Metal. You are the first I've seen.
There will never be a greatest Metal "something" ever and have consensus on that, but there are indeed influential drummers that have shaped Metal as it was and is and I don't think Greiner had anything to do with that. That doesn't mean you can't enjoy his drumming, just saying.
One of my favorite drummers would be this guy:
1. I'm failing to see what's special about this Grenier person. It sounds like the drumming in about 75% of metalcore. But I REALLY dislike metalcore, so I could be biased.
2. That Absu is fucking killer.
3. While we're on the subect of awesome drummers...Quo Vadis drum footage (Silence Calls The Storm): https://www.youtube.com/watch?v=_j_rf_UrsOM
