Blake Shelton had so much fun surprising fans last night (July 27) with his pop-up concert in Kansas City that he's set out for another show tonight in Denver. The "She's Got a Way with Words" singer let fans in on the new gig earlier today on Twitter.

"So much fun I want to it again tonight. Actually I AM going to do it again tonight. Somewhere that's about a 10 hour drive from Kansas City," he writes on Twitter.

Not sure exactly where he is at the moment, Shelton said his new destination could be a nine or 11-hour drive from Kansas City.

He then gave fans a hint on where he is with a picture from his bus window before revealing the final location: Grizzly Rose in Denver, Colo.

Once again, the show tonight (July 28) is free and first come, first serve.

"I haven't been to the grizzly rose in years... This will be epic," he concedes

Shelton began the week of surprise concerts yesterday during his day off. The singer also made the announcement on Twitter during a series of cryptic tweets.

In the span of a few minutes he went from “Where should I go?” to announcing a free show at Whiskey Tango in Kansas City, Mo. The venue later posted a Facebook update, saying the first 2,500 people age 21 and up will get in for free.

Shelton’s next scheduled tour date is July 30 in Camrose, AB, Canada at the Big Valley Jamboree, which leaves one day open on his calendar. Will he announce another surprise show? Remember he also played an impromptu show in Alabama earlier this year. Several outlets are reporting that his partnership with Smithworks Vodka is part of the non-tour tour.

Blake Is Truly Unforgettable!
