I'd add that Unmade Bed sounded like a pared-down Diamond Sea, Kim Gordon/Arthur Doyle was not entirely different from Panty Lies and that Pattern Recognition sounded as though it could have been left over from an older album.
(As you might have guessed, I wasn't wild about Sonic Nurse.)
I think these comparisons are kind of superficial. It's one thing to note the reuse of a riff from a recorded improvised performance, a la a lot of stuff off of SYR1 and SYR2 (riffs from these two, as I'm sure you all know wound up on A thousand leaves). The fact that Unmade Bed "sounds like" the diamond sea is probably better attributed to the fact that it was written by the same band (and a highly prolific band at that). I really can't hear the similarity in that instance, other then the consitent songwriting ticks that are uniquely sonic youth's.
In terms of this record I have only heard Reena and Incinerate, but, I will say that they both make me think of the kinds of subtle refinements you hear in "older" musicians who have carved out a unique niche and are willful exploring the intricacies of said niche. In a recent interview (nurse period) Thurston said something to the extent that when he listened to the Youth's older records he was surprised at how some of his playing was in comparison to what he is playing now. I believe he said it sounded like he was playing with gloves on. I think this "chimming" summery sound is a product of an increased sensitivity to clarity.
Anyway, now that I've blown off that pretentious wad, I'm out.
