MOTOR CITY: “There was a thing about Detroit that embraced the Geils Band because we just worked so damn hard.”

There’s a dirty little secret about the J. Geils Band — one that diehard Boston fans don’t always appreciate hearing. In the band’s ’70s heyday, Boston may have been their home, but Detroit was their home away from home. In fact, when in 1972, two years into their deal with Atlantic Records, the Geils Band recorded Live: Full House, they did so in front of an audience at the Cinderella Ballroom in Detroit, not here in Boston.

Now Geils frontman Peter Wolf is once again gearing up to face a Detroit audience: on February 8 and 9 he’ll be out in front of a full house of 18,000 people at the Joe Louis Arena in the Motor City. Only this time it won’t be with the Geils Band — it’ll be as a guest of Detroit-bred rap-rocker Kid Rock. And rather than bringing along his own group, Wolf will be hitting the stage with Kid Rock’s band to play at least a couple of Geils nuggets. When I reached him by phone in Evansville, Indiana, where the tour started on January 25, he hadn’t settled on a set list for his segment of the show, and he was keeping his cards pretty close to his vest. “We’re out here for four or five days figuring it out. The Kid said, ‘Pete, whatever you want to do.’ So there’s some Geils stuff, and I might throw in a couple of solo things, and we’re also working up a Motown tribute where we’ll be doing some Temptations stuff. And since we both love country, we might also be doing a Hank Williams tune.”

Even after just a couple of days away from Boston, Wolf is feeling the vibe of being back in the Midwest. “I’m here in the heart of the country,” he enthuses. “This is where people work hard, if they can find work these days. And they party hard, which means lots of Jim Beam and beer. And they still value and love rock and roll. The Midwest was always such a great supporter of the Geils band. It’s different from the East or West Coast because it’s all blue-collar. They don’t have much money, so when they spend it on something, they’re expecting something in return. When we first got into Detroit with MC5 and the Stooges and Mitch Ryder, there were just a lot of great bands. And there was a thing about Detroit that embraced the Geils Band because we just worked so damn hard. I’m not saying we were better than other bands. But energy-wise, we worked like five times harder than most of the bands we played with.

“In that era, when we started performing, they had these package tours. I think one of the first ones we were on was with the MC5, Iggy Pop and the Stooges, Alice Cooper, Bob Seeger. And when we hit the stage in Detroit, the crowd just went crazy. It was like an instant love affair. They just got it. It was a very powerful thing. There was something innocent and honest about it.”

Wolf is back on a package tour, or a revue of sorts, with Kid Rock, who also invited Reverend Run from Run-DMC and former Allman Brothers Band guitarist Dickey Betts. (Wolf is currently scheduled to stay on board for 11 dates, beginning in Evansville and going up through February 16 in St. Louis.) He first met Rock through Atlantic Records co-founder and long-time executive Ahmet Ertegun, who had a hand in signing the Geils Band back in 1970 and was also involved in Kid Rock’s career. “Ahmet introduced me to the Kid as the kind of guy who has the same kind of energy and feel as I do. And Kid Rock reminded me that there’s this certain thing that comes from Detroit, even though he is into different kinds of music. So I went up to New Hampshire to see Kid’s show, either last summer or the summer before, and he asked if I’d be willing to do a number with his band, and we ended up doing a couple numbers, and it just went really well. And then we met a couple of other times at the Rock and Roll Hall of Fame, and we hung out there chatting about music and just spent some evenings getting into trouble, shall we say, in a way that many of my contemporary rock-and-rollers no longer do.”

At the time, Kid Rock was working on his latest disc, Rock N Roll Jesus (Atlantic), and trying to come up with a way to spice up the tour that would follow its release. “He wanted to put together this sort of revue of music that affected his life growing up in Detroit. So they were coming up with names, and they came up with Reverend Run, and then my name came up as someone they could invite out as a special guest, just to introduce me to an audience who knows the stuff but who never got a chance to see the Geils Band. And then he asked for Dickey Betts, too. So it’s kind of an interesting thing: he goes out and does his thing and then he invites each of the guests out to be backed by his band. In this very corporatized world of rock and roll, he’s into giving the audience their money’s worth, so there’s a similarity there with the Geils Band, even if the styles of music are very different.”

It’s been six years since Wolf’s last solo album, 2002’s Sleepless (Artemis), but when he returns from the Kid Rock tour, he’ll be getting back to work on his next one. He hasn’t revealed much about what he has planned, other than that the guest list includes Merle Haggard and Neko Case. He also recently spent time in the studio with Shelby Lynne. “As someone who makes records, and who has been doing this for most of my life, I still have a certain commitment to what a record should be. I think a good album has to have a beginning, a middle, and an end. I just feel that’s my obligation. So that’s another reason it takes time to do it right.”
