SiJ is a Progressive Electronic project from Vladislav Sikach founded in Ukraine in 2011. The whole idea of the project is to experiment with dark ambience and industrial elements, somewhat in the same style as some of the Bass Communion albums. The project also utilizes field recordings. The project started releasing albums in 2011, and has since released 16 full length albums, the last of which is called "The Utumis Shrine", released in August of 2019. This album has only two very long tracks with a total run time of over 84 minutes. Sikach plays all of the instruments, but does have help with the vocal effects.
