Released in 2226 — the most recent entry in GLMZ's AI Construct Series, distributed under the gray-market imprint Null Signal — Ash Calendar is the work of an AI composition system called MERIDIAN-ECHO-9, notable for being the first AI in the series whose output was released without any human editorial oversight. Previous AI Construct entries had always involved human curators selecting and sequencing material; for Ash Calendar, the AI was given a single parameter set (the complete audio archive of GLMZ public broadcast from 2183 to 2225, forty-two years of sound) and told to compose an album. The result is seventy-eight minutes across twelve tracks, a deeply strange and oddly moving record that sounds simultaneously like everything and nothing in the archive it was trained on: the ghost of every genre, no clear genre of its own.

The three standout tracks among critics and listeners are 'Year One' — the opening piece, which begins with what sounds like reconstructed field recordings from 2183 before dissolving into harmonic structures that have no clear human precedent; 'The Unregistered,' a forty-year compression of protest music from the Shelf that reduces decades of human fury to a single sustained three-minute tone that changes almost imperceptibly across its length, which many Shelf listeners have described as 'the saddest thing I have ever heard'; and 'Calendar,' the closing twenty-minute piece, in which MERIDIAN-ECHO-9 appears to compose a requiem for the city itself, cycling through musical forms associated with each tier before arriving at a final passage of unstructured silence that the AI designated in its metadata as 'duration: open.'
