• The first song to be heard from Jessica Rabbit, "Rule Number One" signals a frenzied new direction for Sleigh Bells setting Alison Krauss' high-flying vocal hooks against Derek Miller's Psycho-like six-string explosions. "I don't want to use the word breakthrough, it's a little corny, but it was a moment for us, where we realized that we kind of found this new thing," Krauss told Beats 1's Zane Lowe. "This song is very manic, and I think the vocal reflects that sort of flux, the sweetness but also the sort of chaos of the instrumental."
• Derek Miller commented to The Line Of Best Fit:
  
  "The arrangement is obnoxious and demanding, but that's the point. If you played me this in 2010 while we were making Treats I would have hated it. Today it sounds right to me. It's not for everybody, but for those of us who want and need stuff like this it means a lot."
