Celtic Cross is a saga created by Simon Posford of Hallucinogen together with Saul Davies and Martin Glover. Saul Davies is known from James, and his work with Mark Hunter on Watershed. Martin Glover from The Orb comes to this project after previous work with Blue Pearl, Adam Ant and Ben Watkins. This collaboration was produced by Youth and Simon Posford.

The style of music could be described as psychedelic rock, ambient and dub music with ethnic influences. Their only release is “Hicksville” and a remix version of it titled “Hicksville - Remastered & Remixed”. Besides “Hicksville”, they also produced a couple of tracks which appeared on compilation albums. The cover of the Hicksville was designed by Mark Neal, the same artist who worked on Posford’s Twisted and The Lone Deranger, as well as the Shpongle albums.
