The following description comes from the event organizer.

Mixing black metal with atmospheric textures, gothic doom, and flourishes of neo-folk and post-rock, Portland, Oregon's Agalloch quickly developed a rabid cult following upon the release of their debut album, Pale Folklore, in 1999. The band issued four more boundary-pushing and critically acclaimed full-length efforts, including The Mantle (2002) and The Serpent & the Sphere (2014) and a handful of EPs before officially ceasing operations in 2016.

Founded in 1995 by guitarist and vocalist John Haughm, the band initially operated as a duo with Haughm joined by keyboard player Shane Breyer before expanding into a four-piece with the arrivals of guitarist Don Anderson and bass player Jason William Walton. The quartet recorded the demo tape From Which of This Oak the following year, with a second demo, Promo 1998, arriving two years later. The latter caught the attention of the End Records, which signed the group and released their debut album, Pale Folklore, in 1999. Eschewing the more traditional black metal approach of the demos, the LP retained the icy soundscapes and supernatural vocals of the genre while introducing elements of neoclassical and folk into the mix.
