Bringing together over 700 pages of drawings and collages, this unique publication immerses the reader in Matt Mullican's creative process by reflecting the 'person' that emerges during his self-induced hypnotic states. 'That person's work' has developed out of Mullican's hypnosis performances (1977-present) and, more recently, photography, drawing and object-making that he has created during a trance state. The artist has described the person that emerges during these performances as 'a sensual, impulsive, almost hedonistic individual with a highly developed sense of humour and theatre, lying somewhere between schizophrenia and autism.'

That Person's Workbook is an artist project made by 'that person', acting like a 'talisman' for a world in which that person exists. Accompanying extensive full-colour illustrations, an essay by Ulrigh Wilmes and an interview with the artist by Vicente de Moura explore the importance of hypnosis and imagination in Mullican's work.
