I don't think it requires that much communication to play blues -- you should be able to fit in with any ensemble.
You really want to make a statement like that? The way you fit in is by communicating, even if it's the receptive kind of just listening before you play. Not communicating to me is the same thing as not listening.
Even in blues, there are enough different substyles, and enough individual approaches, that you have to listen and figure out what's going on. You can't just go on blues autopilot and expect that much good music will happen.
