This might be an odd comparison to make, but I found A Scarcity of Miracles to be aesthetically similar to late Talk Talk. Not a bad thing at all. Good album.
Wrongheaded to assert that this is anymore Crimson than any of the other ProjeKts though. I hope we aren't doomed to have this "is it Crimson or not?" debate for the rest of our lives. (Or Fripp's...)
"I suppose it compares to King Crimson in the same way that On An Island compares to genuine Pink Floyd." That's spot on. On An Island conjures a lot of Floyd comparisons, but in some ways it's vastly different. Same with this record. I can't really even think of much old KC to compare it to. It's more in line with Fripp's ambient work, especially with Eno.
