Well I am not the Original Poster, but I can always hijack this thread.
There's a part where there is this repetition of pattern, roughly slowly goes like :
fa# mi fa# re do# re si la si sol fa# sol
mi re mi do# si do# la sol la fa# mi fa#
re ...
then there's some little thing to redo the patter again, and then another part of the piece comes in. So it kinda looks like a poem, in like an abcbdb kind of structure.
It would seem like it is a more modern piece, which is why I never have heard of its name.
