Florence and the Machine is a fabulous English pop act whose debut album Lungs hit No. 1 in the U.K. charts but never quite managed to crack the Top 50 in the U.S. I'm pleasantly surprised that MTV has paid so much attention to her this year. As for tonight's performance, wow, this woman can sing. The happy tribal chanting works well for Florence, although she seems to have chosen spastic minijumps as her signature dance move. I love her dress.
