This volume — no. 30/31 — is called Memoryville Blues (taken from John Grant’s story by that name) and includes 25 stories by a diverse group of authors including Lavie Tidhar, Mike Resnick, Scott Edelman and Anna Tambour. It was edited by Peter Crowther and Nick Gevers.
Moore’s story was inspired by the Biblical Book of Revelation, but it’s not the usual version of that tale.
The book is available along with many other fine limited editions on the PS Publishing website. Copies should be available in the dealer’s room at the World Fantasy Convention in Brighton, England, over Hallowe’en weekend.
