Known Unknown has been played on NTS shows including Jenkem Magazine, with Chaos Edit first played on 12 June 2021.

Known:Unknown was an alias used on Moving Shadow for a series of remixes by well-known, but anonymous Drum and bass artists. The only release was a remix of Drum Trip. The "Chaos Edit" is actually by artist Dom & Roland.

Most people tag these two tracks as "Known Unknown" because on Windows you can't have a ':' in the file name. But, it clearly says "Known:Unknown" on the label.
