When John Fullbright plays at Rozz-Tox on May 30, expect a certain amount of ambivalence from the songwriter and musician.

I asked him in a recent phone interview whether he considers himself a good performer. "I think sometimes I am," he said plainly.

It's not that the 25-year-old Oklahoma native and resident doubts his chops, which earned him a Grammy nomination for his debut album, From the Ground Up. Rather, he's not particularly comfortable in front of an audience.

"I don't like getting on stage and saying the same jokes and doing the same thing and having a show," he explained. "But at the same time ... that's what people are paying for."
