Young Mountain is the first EP by the American band This Will Destroy You. It was originally self-recorded and self-released in 2005, and was intended to be a demo to be sold after local shows. Although it was then only available as a CD-R, the EP began to receive press mentions. The band soon attracted the attention of Magic Bullet Records, who repackaged the record and released it in CD format in June 2006. This was followed by a cassette release in December of the same year and a vinyl release the following March. The EP has generally received positive reviews, including being named best album of 2006 by the editor of Rock Sound magazine, Darren Taylor.
