"We're creating a show that is going to be remarkable for our fans, but as I'm here today and backstage and we're preparing to come out, I feel like it's going to be one of the most remarkable experiences for us as well," Hill said.
Hill and McGraw are preparing to headline a limited run of shows at the Venetian called Soul2Soul. It will mark the first time they have performed together in the U.S. in six years.
"We can say that the production is going to be very cutting edge. We want to do really cool stuff, things that certainly we haven't done before, and probably some things that haven't been done before," McGraw said.
McGraw has sold 40 million records worldwide, while Hill has sold 30 million. They have a combined eight Grammys, 14 Country Music Awards, 14 American Music Awards and 26 Academy of Country Music awards.
The married couple takes the stage in Vegas beginning Dec. 7 for four shows a weekend, 10 weekends total through April. They will be performing together most of the time.
"It's a different way to see what we've done for years, and it's a different way for us to perform what we've done for years," McGraw said.
Both stars are used to playing to crowds of 50,000 or more. The Venetian venue will be more intimate, with a crowd of about 1,800.
Hill says there's no secret to being a couple on stage and off.
"You have to walk this life together, and there will be ... ups and downs, but you just essentially have to like the person that you love," Hill said.
Tickets go on sale to the general public Monday at 10 a.m. Prices range from $95.50 to a VIP package that will set you back $1,000. For more information, visit the Venetian website's Soul2Soul page.
