That's a quote that holds true in my experience, as mentioned before. Their music is great and the visuals captivating and imaginative, but the band members don't have stage presence. And that's ok. But it's true, they just play their music, which was great.
I've gone to plenty of concerts where the musicians were so absorbed in their music and had NO light show/effects and those concerts were great too, for the music. And that's the bottom line for me. Other effects are just superfluous and not necessary to "support" the music.
