I gotta cut to the chase. I love all sorts of music, from folk to jazz to classical to rock-and-roll, so long as it has some appeal for me. What I have never bought into is the "performance art" that is so stagey and calculated that it overshadows the music entirely. Rock bands are most guilty of it - pyrotechnics and gyrations, not to mention outrageous costuming at the expense of whatever the music says. My favorite "visuals" are those where the performer(s)seems to be thoroughly enjoying the moment. That says two things to me. One, the musician is competent enough to be relaxed in the performance, making it seem rather effortless. Two, he or she is enjoying playing the music, deriving joy from the shared experience.
