The other is a collection of recordings of original compositions that form part of his latest musical concept, ZIM Music, twelve works that run for a total of more than 11 hours and are released on a single Blu-Ray disc.

ZIM Music is based on a principle Braxton calls "gradient logic" that essentially boils down to music which constantly changes its mind. In the accompanying booklet to the Blu-Ray, Braxton himself describes ZIM Music as "a glider airplane that circles in a downward and/or upward spiral." This music constantly changes in tempo, volume and demeanor but at a gradual pace, allowing it to gracefully alter its shape and focus as different instruments either join in or fall out of the mix and come to the front or recede into the background.

The performances of these twelve compositions come from live concerts in 2017 and 2018 and are by six, seven and nine piece ensembles. All have a configuration of mostly horns and strings, with the core musicians on every piece being Braxton himself on reeds,
