Debbie Harry is about pulling off the impossible. Her vocal performances shouldn't work: how can you sound distant and intimate at the same time? You can't, and definitely not in a pop song. Yet Harry does. Her stage persona--the untouchable glamor girl who still shows every ounce of her vulnerability--should be a train wreck (file under "Love, Courtney"). Instead, the front woman's presence has helped propel a four-decade career for Blondie. Pop music owes this band a lot. The new wave pioneers spent a decade in the 70s and 80s experimenting with an eclectic mix of musical styles like disco, hip-hop, and reggae, inviting the predictable wrath of punk's self-appointed bore brigade. But it's hardly an exaggeration that Blondie opened up more lanes for more artists than any New York band since The Velvets. And they're not stopping. Friday sees the band complete an 18-city tour with fellow path-breakers X, at the Roseland Ballroom, and then it's back to the studio to complete their 10th album, tentatively titled Ghosts of Download and due out next year. We sat down with Harry to talk about sexual personas, World Beat, and what "selling out" really means.
