The really really low bass/white noise energy is difficult to do well without impacting other elements, and to my ears this piece does a superlative job in a big complex mix--thanks for posting this! The structure is intriguing--I hear these episodes separated by very short synth noise sweeps as sort of 'instant transition'.
Because of the title and liner notes, I'm sorely tempted to think that these different themes have a specific meaning for the composer, that they related to a sequence of experiences actually lived through or imagined.
I find myself listening to it for leitmotiv's, trying to figure out what each one means in the extra-musical context. This music is definitely telling a story...I just don't know the actual details.
