After suffering a brain aneurysm in 2015, folk/jazz legend Joni Mitchell began hosting private jam sessions at her LA residence to assist her recovery, and notable musicians including Elton John, Paul McCartney, and Harry Styles turned up to lend a hand with musical therapy. One guest, beloved singer-songwriter Brandi Carlile, made it her mission to get these "Joni Jams" to the stage; first with a surprise appearance at Newport Folk Festival, and now with a three-day concert at the scenic Gorge. Carlile will headline the first night, Mitchell the second night (her first headlining show in over 20 years!), and country supergroup the Highwomen (consisting of Brandi Carlile, Natalie Hemby, Maren Morris, and Amanda Shires) taking the stage on night three alongside Tanya Tucker.
