There is good stuff out there. I watched Pantheon and Scavengers Reign recently, both excellent, but not old stable anime.

However both Scavenger's Reign and Pantheon feel distinctly different from Japanese anime. They have a much more Western aesthetic eye visually, narratively, and especially in terms of music I feel.
(Same goes for Solaris, although Tarkovsky's adaptation reverses that.)
To me it looks like Greg Egan's Permutation City, which I found via HN and which made me inhale about seven more of his books in quick succession.
To anyone who's consumed both - is it actually like Permutation City? Or is that too much to hope for?
I'll check it out!
