Well, I do, have you ever think about the invisible wall between the musicians and the crowd? Well, some years ago I was talking with a colleague at a festival about the lights and he said a universal truth about this. He said "The lights are the wall between people and rock stars, they make the difference between people ans stars" and that's true, I was in between in around 400 concerts, and the energy there its unbelievable, it´s like a gigantic wave. I'm an energetic vampire and need more and more jojojojo ;)
