Kenny Chesney's Preshow Ritual

''We have a vibe room backstage,'' says the country-rocker, 38, who just announced summer tour dates. ''We crank up music, and everyone from the crew to family and friends take a deep breath, let go of whatever is bothering us, and shake out all the kinks. It helps me give 100 percent of my energy to the audience. We do that every show night.''
