Genesis Breyer P-Orridge, co-founder of Throbbing Gristle and Psychic TV, has been diagnosed with chronic myelomonocytic leukemia. According to a recent Facebook post, “serious treatments” are set to begin on October 23, and Psychic TV’s upcoming tour dates in Europe have been postponed as a result. “We kept hoping we’d be OK but today heard the illness has got worse this week. My sincere, oh so sad apologies for all of you who bought tickets,” P-Orridge wrote in the statement. “We are heartbroken to have seen the insane amount of work Matski and Edley [ODowd] have put in to set all this up only to have my old 67 year body say it needs a rest. We’ve been touring for about 50 years now. It’s the first time we have had to do this. We hope it will not be necessary again.” Find the full post below, along with a written statement from P-Orridge’s representatives.

This past summer, Psychic TV reissued 1984’s Pagan Day and 1988’s Allegory and Self. Revisit Pitchfork’s “In Sight Out” interview with Genesis Breyer P-Orridge.
