Steve Poltz considers himself more at home in a hotel room than at his beach-accessible San Diego home. Many artists say they tour year-around, but Poltz truly does. Often when he plays a city, he comes back and hits it again within weeks, and then again. "No two shows are alike," he says. "So if you saw me at Joe's Pub in New York last month, you'll get an entirely different show the next time." Seeing that shows are unscripted, with no set lists, fueled only by the spirit of the audience, a growing legion of fans returns two and three times per year.
