Written by Mark Savage — The gig, in Arkansas, offered a glimpse of how live music could resume in the UK, with compulsory temperature tests and social distancing for all present.
Concert-goers were required to buy seats in clusters, branded "fan pods", and large areas were roped off.
"It's just nice to be doing something that's normal," said one attendee.
McCready's concert was originally scheduled for Friday, 15 May, in Fort Smith, Arkansas, but Governor Asa Hutchinson said it failed to meet the state's public health standards.
The venue - a former Masonic temple called TempleLive - was threatened with a cease-and-desist order and had its alcohol licence revoked.
But after making adjustments to their concert plan, the venue received permission to stage the concert on Monday night.
Under the state-approved plan, all employees and audience members over the age of 10 were required to wear face coverings, and performers were instructed to maintain a minimum distance of 12 feet from the audience.
The state also allowed TempleLive to have 239 people seated in the 1,100-seat venue.
'Fight for your right'
After receiving the go-ahead, representatives from the venue maintained they had delayed the concert against their will.
"This is about rock and roll, and having a good time, and live music, and being out with your peers, and doing what you do as an American: You get out, you do things," Mike Brown told reporters at Arkansas TV station KFSM-TV.
Speaking to the New York Times, Mr Brown also argued that concert venues were being held to stricter standards than other public gatherings.
"If you can go to a church and it's a public assembly, there is no difference," said Mike Brown, a representative for Temple Live. "How is it OK for one group to have a public meeting, and it's not OK for a music venue to have the same opportunity?"
State officials argued that a concert was more dangerous than a religious gathering because it was more likely to attract visitors from out-of-town.
When the show finally went ahead on Monday night, Mr Brown greeted the audience by playing the Beastie Boys' Fight For Your Right (To Party) before introducing support act Lauren Brown.
McCready took to the stage later, without referencing the strange circumstances. Nonetheless, fans seemed to appreciate the show.
"We're happy to be here," said LaLisa Smiddy, who drove four hours to attend the concert.
"I'm one of the more paranoid ones out there, and when I saw everything this venue has done, I was ready to come," she told the New York Times. "I think they've done an outstanding job."
