13 Blues for Thirteen Moons is the fifth full-length album by the Canadian post-rock group Thee Silver Mt.

[6][7] The album consists of an instrumental feedback intro, split into twelve extremely short tracks, and four full songs, which had been played live on recent tours.

[8] Band member Efrim Menuck stated that the idea for the 12 short intro tracks initially was suggested because the band wanted the album to start on track 13.

"[9] The liner notes are found in the CD booklet titled Himnos de Sion—Spanish for "Hymns of Zion".

The booklet also contains lyric sheets, presented in the block-capital handwriting familiar with owners of other Silver Mt.
