A few times I have found it hard to accept artists because I felt they were too hung up on their persona or appearance. Or just not authentic enough. Elton John, Zeppelin, U2 are in there. In fact, I cant name even one KISS song. They might be a great band for all I know, but the facade is repellent.
Theatricality can be different. Floyd used a lot of props, inflatables etc. Although its image specific, its about song subject matter rather than THEM. They certainly did have an image of themselves but it was not entirely unreasonable.
Los Lobos have seemed quite self effacing for the whole of their long career. They often drape a religious looking backdrop behind them, suggesting catholicism, though I have never heard any of them speak of belief. Did they use image? Not that I can see.
