Nashville roots-rocker Jon “the Doctor” Roniger performs a set of acoustic songs from his two CDs at the Barking Spider tonight. On 2004’s Addicted, the former choirboy slams a pair of past vices: booze and cocaine. “The songs were written when I was drowning in a sea of self-destruction,” he says. “I went through many changes in my life.” A year later he released My World, a 10-track tribute to sobriety. “I’m never going to get rid of the addictive personality, so I’ve refocused my addictions to healthier things,” says Roniger, who names John Mellencamp and Tom Petty as influences. “I’m equally addicted as I’ve always been. I’m just now addicted to things that are a positive force in my life — like music.”
