MEMPHIS, Tenn. — Jason Isbell and the 400 Unit have been added to Graceland Live’s lineup.

According to a release from Graceland, Isbell will be joined by singer-songwriter Brittney Spencer. The concert will be held October 8 at the Soundstage at Graceland.

Isbell was slated to headline the 2021 Bristol Rhythm and Roots Reunion, but earlier this week, he announced he will not be performing. His announcement came after Rhythm and Roots organizers revealed attendees would not be required to show proof of vaccination nor a negative coronavirus test.

Isbell had previously announced he would be requiring those attending his performances to show proof of vaccination or a current negative test.

Graceland Live is reportedly requiring all attendees to either have printed proof of a negative COVID-19 test within 48 hours of attending or be fully vaccinated. Graceland says unvaccinated guests younger than 12 will be required to take a COVID-19 test within 48 hours before the event and show proof of a negative result prior to entering the venue.
