Morgan Wallen ran into some technical difficulties during the Denver stop of his Still the Problem tour on Friday night (May 29).

While seated at the piano to perform “Sand In My Boots” during the first of two shows at Empower Field at Mile High, the 33-year-old country superstar appeared frustrated after seemingly being unable to hear the instrument properly.

Wearing a Colorado Rockies Todd Helton jersey over a black shirt, matching shorts and a backward hat, Wallen abruptly stood up mid-performance and pushed the piano over before finishing the song a cappella. “Sand In My Boots” topped Billboard’s Country Airplay chart in February 2022.

Fans seemed to embrace the candid moment, with many praising Wallen’s solo vocal performance in the comments section of an Instagram post featuring fan-captured footage of the incident.

“No piano needed..give it up!! Sound better without it!!” one person wrote. “Imagine he’s giving us this beautiful Acapella solo and all he’s thinking about is pushing that pos piano over,” another commented “This man doesn’t need any background music when he is unplugged. He is the ultimate a acappella singer,” a third commented.

As has become tradition on the tour, the “Last Night” singer opened Friday’s show with a walkout appearance alongside legendary Denver Broncos quarterback John Elway.

The concert also featured opening performances from Brooks & Dunn, Gavin Adcock and Zach John King.

Wallen is set to return to Empower Field at Mile High for a second Denver performance on Saturday (May 30). After that, he’ll head to Pittsburgh for back-to-back shows at Acrisure Stadium on June 5-6. The singer currently has multiple U.S. stadium dates scheduled through August.

Wallen is touring in support of his latest studio album, I’m the Problem, which debuted at No. 1 on the Billboard 200 in May 2025. The project went on to spend 13 nonconsecutive weeks atop the chart.
