Sagarmatha is the seventh full-length album by Lawrence, Kansas-based indie rock group the Appleseed Cast, released on February 17, 2009 by The Militia Group and Vagrant Records. The album was also released on double LP by Graveface Records; the vinyl version has an alternate track listing and one additional track. The album's title is derived from the Tibetan word for Mount Everest, which guitarist Aaron Pillar learned while reading Jon Krakauer's 1997 book Into Thin Air.
The album began life as an instrumental EP, which was then stretched out as the band returned to techniques they had previously utilized when writing and . According to Pillar, Sagarmatha was conceived as a concept album that revolved around "zombies and an apocalyptic future." Half the album was recorded at the band's home studio the Toy Shop, and the entire process lasted approximately nine months.
