Chattanooga's Moon River Music Festival lost one of its headlining acts Wednesday, three days before the start of the festival.
Caamp, a folk band from Ohio whose songs include "Vagabond" and "Apple Tree Blues," announced on social media it is canceling all of its shows for the rest of the year, including its appearance at Moon River.
The band was set to headline the festival Saturday, its first day. Hozier, an Irish singer-songwriter, is slated for the top spot Sunday.
"In the past few months, I have experienced some untimely knocks to my health, and the mental side of things isn't where it needs to be," a post on the band's social media said Wednesday. "I am not well enough to give you my best. The band and team are in full support, we need some rest."
The post was signed "T," for founding member Taylor Meier.
Caamp said it plans to refund tickets for its canceled solo shows, but it's unclear how its cancellation will affect Moon River ticketholders.
The festival reposted Caamp's announcement on social media, where commenters lamented the cancellation and suggested other artists they'd like to see take the band's place -- including folk artist Noah Kahan, folk rock band The Avett Brothers and country artists Zach Bryan and Tyler Childers.
"We will miss them dearly and wish them the best in their journey ahead," the post from Moon River said Wednesday. "Stay tuned for updates coming soon!"
Tickets for the festival sold out in less than a week, organizers said previously.
Moon River was founded by musician Drew Holcomb, who moved the festival to Chattanooga from his hometown of Memphis in 2018.
