Well the outfits she chose when she was promoting Blonde were terrible. Now I don't know if she had put on a few pounds back then, if not, the outfits certainly made her look like she did. She's still incredibly beautiful when packaged the right way.
I liked the song Alcaline from the beginning, but I didn't listen to it that often. Then I put together my video and now I listen to it almost every day, because as with her early songs, that reminded me of 'seeing' those beautiful early performances on stage, now Alcaline reminds me of the beautiful images in my video. She could have been very beautiful for Alcaline, but poor choices on her part negated that. There was really nothing worth remembering imo, during the Blonde era. Another good song from then; K.O., she didn't even promote.
EDIT: The ironic part about the Blonde era was there were so many times she looked great off stage. It's only when she was on stage singing her own songs that she looked terrible.
