In Ubahn c. 1985: the Rosenberg Variations  a rhizomatic, rather than single plane score model was also introduced to the Decibel Scoreplayer, in which interlinked staves (or paths) could be freely traversed by the score-reader. Two new works trash vortex  and detritus , feature scores comprising three layers: a graphical score, a rhizomatic path and a image collage (left). The “path” layer periodically (and indeterminately) becomes transparent causing the graphical score to appear to "submerge" into the background collage - making it more challenging for the performers to read. The scores (in the Decibel Scoreplayer) send messages about the “path” layer's status via OSC to a MaxMSP audio processing patch, which in turn alters the audio processing of the live instruments to reflect the state of the score.
