a new note to add to the thoughts on schism:
To begin, we start with one distinctive riff. It represents a sense of harmony unity and calamity in one. Inturrupting the peaceful existence of this "being" is the introduction/presence/birth, whichever you will, of the new presence symbolised through Adam's guitar work. While both of the beings harmonise, one can still feel the building tension between the two "persons". This finally errupts into the heavy, pseudo undertow feel, in which the two fly back and forth drowning each other out. It eventually passes into the conclusion in which both collide and merge into a single riff/existance where, despite retaining their differences, enter a near perfect synergy...
The final riff ensues... The song and being are complete.
