PENDLETON â The Pendleton Whisky Music Fest will be back in 2021, but it will look significantly different than anticipated. A year after event organizers were forced to cancel the concert due to COVID-19, Whisky Fest announced it would come back on July 10, albeit with new headliners. Facing a 12,000-person capacity limit at the Round-Up Grounds, Whisky Fest is postponing previously announced headliners Macklemore and Eric Church to 2022 and bringing in a new slate of musicians. Whisky Fest will announce its new headliners on May 28. According to Whisky Fest co-founder Andy McAnally, trying to organize a concert as reopening standards shift was a challenge.
