Taylor Swift at Staples Center. Even the nosebleeds were freakin' expensive, but at least we were dead center so we had a great view of the stage, the tree, and the spotlights.
She still isn't all that great live, but she's very good at appealing to the crowd and is very expressive as she sings. An audience full of screaming little girls (and their parents) probably isn't too hard to appeal to either, I think we were the only people older than 25 in the crowd who weren't toting kids around. o_0
