I suppose it depends somewhat on one's own personality. Some folks are flash beggars, wanting to be noticed, others are more discreet, not wishing to draw attention to themselves. For my part, I've no wish to be forward, and the bass players I appreciate the most I recognise more for their musical abilities than anything else. Many I've never seen, in picture or live, so wouldn't know how they project themselves. To me, it's an irrelevance. Good playing is good playing, whether out front or backing another. Simple, really.
