Sex-powered soul superstar Beyoncé brought the house down tonight at the 2011 Glastonbury Festival in Somerset, England. Here's the opening number: a pyrotechnically enhanced version of her defining single, "Crazy In Love." Reviews of the performance — which included familiar hits like "Single Ladies (Put A Ring On It)" and "If I Were a Boy," alongside covers of Alanis Morrisette's "You Oughta Know," Eurythmics' "Sweet Dreams," and Prince's "The Beautiful Ones" — have been glowing. The Guardian declares "she never puts a foot wrong," and The Telegraph calls her "a great, sassy frontwoman."
