Some drummers' nervous ticks are distracting. For example, I'm not crazy about the constipated facial expressions that Paul McCartney's drummer makes. That's probably not nerves, just showmanship, but you know what I mean. Some drummers make weird facial expressions when they play, without thinking about it. I think I do some Stevie Wonder head movements when I play. Do you have any ticks and do they cause you any concern?
