Even a stomach bug can't slow Eric Church down. With most of his crew sick, the country superstar could have cancelled his Saturday night (Jan. 31) concert in Salt Lake City, Utah -- but instead, fans got a once-in-a-lifetime performance.

Using a scaled-back stage setup, Church played an 18-song set mostly solo, just himself and acoustic guitar. He was, however, joined by Lzzy Hale -- whose band Halestorm has been opening for Church throughout his Outsiders World Tour -- on 'That's Damn Rock and Roll.' The stripped-down result was stunning; press play on the video above to see the performance.

“If you’ve seen our show so far on this tour, you’re probably wondering what the hell is going on right now. Well, so am I,” Church told the crowd as he took the stage. “Here’s the deal: Yesterday, we had the stomach flu strike our band, our crew, everyone. We had no one to hang video, lights, nothing. But I’m still here. I’m still standing.

"We've talked about how every show on the Outsiders Tour is different. Well, tonight will be the most different one," he added. "S--t, there’s nobody left. It’s just me. I’m going to give you everything I got.”

Although it's hard to imagine being disappointed to be in attendance for such a unique concert, Salt Lake City ticketholders will get their chance to see the full-scale Outsiders World Tour experience, as Church also announced a makeup show, set for May 25.

The 'Talladega' singer is nominated for four Grammy Awards at the 2015 ceremony, set for Feb. 8; he'll also be performing.
