To me music is about feeling, and by watching a live band more of your senses (visual) are being incorporated into the experience. Going to a live show has always made me appreciate the band more and feel more connected with the music. Anyone who would simply pass on a concert in favor of listening to the band on their ipod at home has probably never gone near a musical instrument before. Think about every awesome drum part you've ever heard... Don't you want to see who the fuck the dude pulls that off? I don't know about this dude, but I certainly do. I could however be biased as I am a drummer myself.
