The Sator Arepo, or Sator Square, is an ancient word puzzle comprising five palindromes that's etched on various historical sites throughout the Western world. Its origins are unknown, but the square has long been thought to hold magical properties, used as a charm against illness and evil, to cure insanity or to determine whether someone was guilty of witchcraft. Self-styled "punk ethnomusicologist", acoustician and musician Julien Hairon uses this mystical symbol as the starting point for his debut Judgitzu album in an attempt to reconnect with his Celtic heritage, exploring how its hallowed messages might harmonize with contemporary Tanzanian dance music.
