Mind-blowingly good. As in "one of the best 50-ish albums I've ever heard". Gorgeous, eclectic, exhilarating-yet-meditative sound. Musically, this goes to more interesting places than Bowie/Eno's Berlin trilogy, and it has a better vibe as well. It's even got proto-punk, along with early post-rock and new-age-ish tendencies. These are all pretty divergent impulses, but they're integrated here just about seamlessly. Ridiculously ahead of its time, so much so that it's essentially timeless.
