Ninety shows. Ninety-nine days.

It’s a tour schedule that few artists in any genre would dare tackle, but it’s the challenge that rapper Tech N9ne was given.

After doing an 80-cities-plus tour last year, the rapper was dared by the business partner in his Strange Music label to tour to the nines.

“That would be ideal,” he remembers responding. “I said, ‘Let’s go.’ I didn’t even question it. I won’t know how hard it is until the 70s. Toward the end of the 82, I started being disoriented and everything onstage. So we’ll see.”

Just more than halfway through the tour, Tech N9ne and other artists from his label play the Davenport RiverCenter next week.

After recent tours of Germany, Sweden and Paris, Tech N9ne says he wants to visit Africa, Ireland, Brazil and Jamaica on tour.

“I’m not content. I still have a lot more places to hit. I shall tread every piece of this earth before I go,” the 41-year-old said from a tour stop in Rapid City, S.D.

The Kansas City native, born Aaron Dontez Yates and named for his rapid-fire delivery — a la a TEC-9 semi-automatic handgun — said that between his own work and acts on his label, he’s aiming high.

“I was going to make Tech N9ne the biggest thing I could make it, and it’s going that route. It goes up, this is a vertical journey, to shoot beyond the stars. That’s what we’re doing,” he said, adding, “I haven’t gotten there yet, but it’s looking very bright.”

He said there is no frustration over younger acts on bigger labels succeeding while he’s running his own independent outfit.

“They have a bigger machine, so it makes sense. I use my own money. I congratulate young cats coming out and making it. But later, I’m still on the incline and they’re gone,” he said. “If they don’t stop to build a fan base, they’ll be gone, a flash in the pan.”

The trajectory analogy continues.

“What we’re doing here is having a good time doing whatever the hell we want to and staying on the incline, staying toward longevity,” he added.

There’s never been a wish to be part of a major label, he said.

“Nothing came my way where I said, ‘We might want to give them a percentage of this.’ We’re totally good over here,” he said. “We’re building something, building an empire. Before you know it, Strange Music will be the major, y’know what I mean?”

He’s at work on a new Tech N9ne album. He won’t even divulge the title yet, but said it’s due out in late October.

“I think it’s going to be amazing because I have a lot of beats chosen already,” he said. “I don’t know what I’m going to say, but I’m going to sit down. And when I sit down, it comes out. Sometimes I want to party instead of sit down and relax. But when I sit down with a pen and pad, it all comes out.”
