Gann became obsessed with it, and once technology allowed him to easily digitize the recording in the mid-aughts he set about transcribing it by ear. Johnson sent him a copy of November's six-page manuscript, but since the composer was in frail health and his memory was failing, he wasn't able to fully explain how diagrams illustrating how the core melodic cells were combined—Gann set about doing it himself based on the cassette recording. Notations on the manuscript were dated 1970-71, while another passage read "Dec. 1988," making the temporal origins of the piece increasingly murky. Gann had heard rumors that November was intended to roll on for six hours, and over the years he fleshed out Johnson's manuscript, adding variations and elaborations based on the composer's notes. He and fellow pianist Sarah Cahill premiered the new version in September of 2009 at the 2nd International Conference on Minimalist Music at the University of Missourri at Kansas City, with the musicians alternating turns each hour. Irritable Hedgehog owner and fellow composer David D. McIntire and pianist Lee were two of the nineteen people at the concert, and they were suitably moved to make this gorgeous recording, which boldly shows off the composer's early embrace of additive composition. New information is slowly added to the most basic materials, unfolding measuredly to create a hypnotizing, beautiful epic. The four discs—totaling just under five hours—are packaged in a glossy cardboard box with an illuminating 20-page booklet featuring essays by Gann, McIntire, Lee, and Mark Harwood.
