The cover marks IDLES' first release of 2021, following their 2020 third album Ultra Mono.
Other artists that have covered songs for epic Ten include Fiona Apple, Lucinda Williams, Courtney Barnett ft. Vagabon, Shamir and St. Panther.
Van Etten says of epic, "epic represents a crossroads for me as an artist -- going from intern to artist at Ba Da Bing, from solo folk singer to playing with a band for the first time and beginning to play shows on tour where people showed up. I am in awe of the artists who wanted to participate in celebrating my anniversary and reissue, from young inspiring musicians, to artists who took me under their wing, who I met on tour, and to artists I’ve looked up to since I was a teenager. Each one of these artists continue to influence my writing and provide a sense of camaraderie during this new era of sharing music."
