The Dead Channel Trilogy (stylized as deadchannel_Trilogy) is a trilogy of studio albums by American multi-genre project Blue Stahli, consisting of the project's seventh, eighth, and ninth albums (if including the instrumental Antisleep series).

[3][4][5] Obsidian was written before Quartz and Copper, and it was originally planned to be a standalone album.

Eventually, Quartz and Copper were written and planned to be released in a trilogy alongside Obsidian.

Blue Stahli founder Bret Autrey's inspiration for the albums came from caring for his terminally ill mother who died in 2018 from brain cancer.

For the other two albums, "Copper achieves the melancholy, experimental soundscape, while Obsidian defines who he is after his mom's death.
