The band was one of several performers scheduled to make an appearance at the Sturgis Buffalo Chip campground, about three miles outside of the city of Sturgis.
In video captured by CNN affiliate KOTA-TV, a large crowd can be seen cheering during the performance, with few masks in sight and no social distancing.
At one point in the concert, a band member addressing the crowd can be heard saying “F*** that Covid s***.” It’s unclear what he’s saying before or after that comment.
The campground, which has often played a central role in the festivities of the 10-day event has added on its own safety precautions this year, owner Rod Woodruff previously told CNN, including signs reminding guests about social distancing and keeping their hands sanitized.
“What’s important for people to understand is in a very small community and rural western South Dakota, you cannot have tens of thousands or hundreds of thousands of people come without preparations, including garbage and sanitation and additional law enforcement and emergency medical personnel,” Daniel Ainslie, the city manager, told CNN earlier this week.
