He is awsome! It's really bad, that the bass drum is too quiet on the DVD, but i really like the sound of his toms.
He also toured with tenacious d.
I'm a huge Bad Religion fan, and some older fans are saying, that live he is not tight enough. I think he is really tight and solid and he is by far the best Bad Religion drummer. I also like that he changes his drum parts and his set up all the time. He hits the drum pretty hard and plays with much energy.
