An outsider Irish artist (died 2009) from the 2015 imaginary art history Historical Documents of the Irish Avant-Garde, assembled by Dr. Jennifer Walshe. An Irish avant-garde artist and composer, she delved into the history of the Irish avant-garde, and not finding enough, made some up.
He created avant-garde recordings on cassette tapes which he manipulated by physical processes such as burying and burning. He called these his "Subliminal Tapes."
In the 1980s he started annotating player piano rolls.
A number of actual audio tracks were recorded for the project: "Subliminal Tape #86" and "Song Roll 5."
