I've also heard War Babies, which was produced by Todd Rundgren who turned it into a Utopia album. Hall's voice already kind of sounds like Rundgren so the resemblance is uncanny. Definitely recommended for Rundgren fans.
Also I've heard Sacred Songs with Fripp which is maybe the weakest of Fripp's late 70s trilogy by a small margin, but is still quite good. those 3 albums kind all blur together with all the song overlap though, so they're kind of hard to separate in my mind sometimes. I kinda think it would be cool if Fripp reissued them as some big triple album with the tracklist shuffled together.
