Communication is not just if the audience gives back. There has to be some sort of interaction with the audience--it's not just one-soded here. Even if the audience loves the music you play, if you don't give them anything else, then it isn't communication--it's like a bunch of people at a party listening to a CD. They can cheer and shout and dance and sing along or whatever, but there isn't any interaction--which is what's great about concerts. The performer's job is to entertain as much as possible, but they should definitely interact. One thing that I (personally) hate is a concert where the music is just fanastic, but the musician/band doesn't talk to the audience at all. That is self-indulgence, too. Just as much as if someone plays just to please themself.
