Rainier Fog (pronounced: ) is the sixth studio album by the American rock band Alice in Chains, released on August 24, 2018, through BMG, the band's first release on the label. The title was inspired by Mount Rainier, a volcano that overlooks the Seattle-Tacoma metropolitan area, and the title track is a tribute to the Seattle music scene. This is the band's third album with William DuVall sharing lead vocals with Jerry Cantrell, and the first Alice in Chains album in 22 years to be recorded in their hometown of Seattle. The album was partially recorded at Seattle's Studio X, the same studio where the band recorded their 1995 self-titled album. Rainier Fog is also Alice in Chains' third collaboration with producer Nick Raskulinecz, marking their first time recording three full-length albums with the same producer.
