Death Cube K is an anagram for Buckethead. He created this name in 1994 to release an album that Sony would not allow due to his contract with Sony for his album Giant Robot.
"Many believe, however, that Death Cube K is a separate entity that looks like a photographic negative version of Buckethead with a "black chrome mask, like Darth Vader." This apparition haunts Buckethead and appears in his nightmares."
Buckethead generally releases his more experimental, dark ambient music under this name.
