Katy Perry messed with her earlier hits Friday night at Target Center with mixed results. The heavy synth-grind update of "I Kissed a Girl" worked surprisingly well, but her jazzy show-band version of "Hot N Cold" felt forced and kitschy. She let her costumes provide the big twist during "Teenage Dream" and "Firework" later in the show, the latter of which found her in an ornate black and red dress with a big bouffant rear that looked like she was wearing a giant fancy vase around her waist. Or something like that.

Both Perry and opener Kacey Musgraves wasted no time talking about their roller-skating adventures at Skateville the night before. Burnsville has never gotten so many more shout-outs in a local sports arena outside of the high school tournaments. Musgraves brought it up right away and bragged, "I didn't fall once. And I brought my knee pads." Perry said, ""It's one of the most nostalgic mom-and-pop skate spots in the country."
