Tiësto is about to make a big commitment in Las Vegas.

No, he's not getting married -- he's inked a deal for a year-long residency in Sin City.

Instead of doing Ibiza, the dance capital of the entire planet, Tiësto is dedicating a full 365 to stateside performances. "I'm going to dedicate my year to Las Vegas. Just Vegas, maybe a couple of festivals," he told Rolling Stone. "I haven't decided yet. With the scene blowing up in America, Vegas is so much fun now," he added. "It's the right time to do it. I do everything on my gut feeling, and I felt like it's gonna be awesome there. I've been to Ibiza for 10 years, and I love Ibiza, but I always look for something new and a new challenge."

Tiësto's residency will be at Hakkasan Las Vegas at the MGM Grand Hotel for 20 months beginning in April 2013. He'll perform 20 daytime shows at the Wet Republic outdoor pool as well as 40 performances within the huge, five-level Hakkasan Las Vegas Restaurant and Nightclub, which has a 7,000-person capacity.

"They want to make it an experience," he said of the Hakkasan. "For sure, the production inside the club is going to be amazing."

And just because it's the same DJ for 20 months doesn't mean it's going to be the same show all the time. In fact, Tiësto promises a new show every week.

"I think nowadays, with people having mobile phones and the Internet, you have to be even more aware that people see the show even before they come," he said wisely. "You have to make sure you can always surprise them every time you do a production."
