Setting their sights even higher, in early 2008, The Kissaway Trail set out to record their sophomore release, and the first for America. They rehearsed in a desolate rented farm close to their home in Odense (Denmark's third largest city, situated on the island of Funen) before shifting to the French mountains to narrow down their material. By the end of 2008, they moved the recording process to Sweden. At the close of the year, and the album nearly done, the band realized it was not the musical vision they intended and decided to trash the record, and begin fresh at the top of 2009. Sleep Mountain, was made at Odense's Lydkraft Studio, where the magic of their debut record had also been created, with their dream producer, Peter Katis (Interpol, The National, Sigur Rós' Jónsi) in just two weeks.

The album isn't so much a reinvention for the Danish quintet, but a fabulous progression. The clanging of church bells on the bombastic opener, "SDP" leads the charge into the panoramic sensation of the album. Sleep Mountain guides listeners through varying moods and emotions with dramatic cadences. Album standout, "Don't Wake Up" is an impressive tune showcasing the use of euphoric electronic sounds and raw guitars, displaying what this band does best. "Beat Your Heartbeat" is one of the most joyous yet melancholic songs on the record with its dramatic drum patterns and multiple vocal chorus repeatedly chanting "they will beat your heartbeat." Sleep Mountain is a contemporary, timeless and vulnerable rock album.
