I think the effect we are hearing is not a defect...it's the desired effect, and it's cool. It's just a little grating sometimes when your looking for a crystal clear harmony. I heard/read it was recorded in an old studio once used by Buffalo Springfield, and the recording sounds like it was kept a bit unfiltered (as if to bring out some of that old magic). Not to sound too sentimental, but a lot of the album sounds like a throwback, and I have no problems with it whatsoever. Even if it wasn't done on purpose.
