Iggy Pop is proud of 'Kill City,' the 1977 album he recorded with late-era Stooges guitarist James Williamson. With Williamson and Pop back together in the Stooges after three decades of estrangement, the project's Oct. 19 reissue couldn't be better timed.

"'Kill City' to me was a very good minor work," Pop told Rolling Stone this week while promoting his new T-shirt line. "It was an important work. It was my indie record."

Originally recorded in 1975 as a demo to shop to labels at a time when the singer was fighting heroin addiction, the disc features such lost piano-laden classics as 'I Got Nuthin,' 'No Sense of Crime' and the title track.

Pop also reported that he and Williamson are at work on demos for their first new collaborations since 1980's 'Soldier.' Pop says that although "the riffs are really good," he's raised the bar for any new material that sees the light of day.

"I'm keen to respect the integrity of the group and what it stands for so I don't want to do a new album lightly," he explained. "Whatever songs we do, I want them to be better."
