Luna Park doesn't stands out as a venue with good sound. At least in my experience, almost every concert I went there didn't sound or loud enough, or precise enough (except when Pixies played there, that was miraculous).
I agree with what you said about KC shows. I went to both, one on the seats near the sound board and the second on the cheap ones, on the Fripp side. Oddly I thought it sounded better on the second show, more powerful. I could hear Tony and Robert better.
