I honestly don't see the point of jumping around, etc. If you do it, that's cool. The pic I attached is from a classic rock gig, not my bag, so the rockin' was minimal from my point. I have the worst stage presence... feet together (no power stance ) looking everywhere but at the audience... sometimes at the band, usually the ground. And to top it off, I always look awkward with a bass in my hands. I don't know why, I never look "cool" playing music. ... I do a little with a guitar though.
