I've seen Chris play live a couple of times (a while back now), and apart from his ridiculous skills, he really gets into it. It tired me out just watching him. 😁
But, when he plays Arco, he can be very gentle and subtle. That's the thing with him, he's very versatile with obvious classical training.
He's a very driving player (on both upright and electric).
I'm surprised he doesn't get mentioned here on Basschat. But, if you do a search over on 'TalkBass', there are a few posts mentioning him.
