“It’s built in the Weissenborn tradition in that it’s got hollow chambers in it,” he explains, referring to the vintage acoustic guitars he used to favour. “But it’s capped like a Les Paul with a maple top over mahogany, so it gets an electric resonance and sustain.”

In layman’s terms, Harper’s lap steel kicks ass. With skilled practitioners like him taking the instrument to a wider audience, it might not be long before would-be rockers start reaching for lap steels in music stores rather than just Les Pauls and Strats. His fiery fretwork—which earned him the cover of July’s Guitar Player magazine—has impressed scores of music lovers, including the more than 100,000 souls he played to at the Montreal International Jazz Festival two months back.

“That’s a heavy scene,” he says of performing to that many people, “a heavy moment in one’s life. And it just so happened to be Relentless7’s best show yet—and it’s on tape! Ten high-def cameras, recording truck. So I think we’re gonna release it pretty soon as a live DVD/CD.”

Until then, Harper fans will have to settle for the superb White Lies and the other fine recordings he’s made, such as 1995’s college-radio fave, Fight For Your Mind, his first of four gold albums. With his 40th birthday coming up on October 28 (“I think about that every day when I wake up and have the sore-back blues”), he reflects modestly on his accomplishments so far.

“It’s a great start,” he offers. “It’s been a series of great building blocks from which to jump off into this new technological age.”

Harper won’t be making that leap alone, of course. As well as recruiting the top musicians to get things done, he’s always willing to seek career guidance from his talented soulmate, who recently won a Golden Globe for her role as Florida congresswoman Katherine Harris in the HBO special Recount.

“Before I got on the phone we were givin’ each other advice,” he explains. “Laura’s not only an incredible actress, she’s the smartest woman I know—I mean, other than my mother, I suppose. I’d be a fool not to bounce stuff off of her.”

A week after our chat Harper is booked to begin a tour with his “dear friends” in Pearl Jam, and he’s particularly psyched about playing with them in Vancouver.

“It’s been one of the best cities on the planet to us,” he raves. “Imagine, from the Orpheum to Deer Lake Park—that’s a dance, man, that’s an incredible experience over a lifetime to be able to have that span and that growth and the ability to share your music with different people in different situations like that. And I just look forward to it growin’ further, so thanks to the city and the heads there that illuminate what I do.”
