"this is the way of the organic society, to flow with time" - Don Cherry [1] Time abstracted and encoded to a calendar: spacetime -> words [2] (~1996 -) DARBOVEN codifies these words using spatial mediators / two-dimensional grids: words -> space [3] then generates written musical procedures over time from this process space -> words [4] these can optionally be performed by a "musician" words -> time DARBOVEN: spacetime -> words -> space -> words -> time [5] (2014) BIRKIN interprets the results of [3] and EVOL produces multiple variations of Opus 17A. These multiple, independent variations can NOT be played simultaneously in time from a single notional space whilst retaining their identity as translations of [3]. Resultingly, their presence is spread back over spacetime. words -> spacetime DARBOVEN + BIRKIN + EVOL: spacetime -> words -> space -> words -> spacetime Thus symmetry - bus 2015 ---------------------------- EVOL - bus017a recorded by Roc Jimenez de Cisneros and Stephen Sharp sequencing by Guy Birkin mastered and cut by Noel Summerville black vinyl with poster insert edition of 300
