In my opinion, he's one of the cleanest metal/-core drummers out there.
Lots of people don't like him because of the 'troubles' As Blood Runs Black has had with keeping a decent line-up,
and many think that he is one of the reasons for these troubles. I think he's a really nice guy, spoke to him on facebook about
his gear and playing and he took time to answer the questions, in a very polite and enthusiastical way.
Anyway, check him out, check As Blood Runs Black out and enjoy their magical music
