Designed by Paul Nicholson in 1992 for the Xylem Tube EP by Aphex Twin. In 2015, Nicholson showed a typeface named Xylem, with a complete set of lowercase characters and numerals. It’s not clear if he had made a font already in 1992, or if the cover showed lettering. In 2017, Nicholson mentioned that the font “will be available soon”.
