This tastes of dark and cyberpunk.
As the name would suggest, Heterotopia deals with the concept of contrast, primarily contrasts between mind and body, life and death, etc, but also the contrast between sameness and change. As topic for a prog rock opera, this is perfect.
And as prog rock, the music is phenomenal. From not-the-same melodies to grand, layered string sections, from headbanger to intelligentsia, this has it all.
My one complaint is that the vocals fall behind the music in volume.
