Sundowner was a project's name in the 413th FTS.[1] Because track length is emphasized with 666, the following track times backwards surrounding the track (935253-704) looks 1337 for pesesh-kef, with Opening The Mouth being roughly twice as long as Sundown. Semena Merkvykh 03i3, appears l337 for OBB, possibly referencing Bobby Bond who died during his farewell flight (~Farewell Fire) or the Church of the Sub Genius.
Speculated to have been a track that was left off of Geogaddi.
