Before you sell a kidney to buy overpriced Garth Brooks concert tickets from scalpers on the internet, let's just wait and see if Garth Brooks' people add some more shows. According to a video he posted on Twitter tonight (July 21) there may be one - or two - more shows coming.

Garth's six shows at the Denny Sanford PREMIER Center sold out in 29 minutes this morning (July 21). That's a whopping 45,000 tickets. The shows are September 15, 16, 17, 22, 23, and 24.
