A recent New York Times profile calls her "Opera's Coolest Soprano."
While I'm always a little suspicious of the press-agency hype lurking behind such epithets, Danielle de Niese certainly is a performer of charisma and pedigree. She just released a new Mozart CD, and this summer found her back at Glyndebourne Festival Opera, where in 2005 she showed off not only her ability to fearlessly tackle Handel's soprano fireworks, but also to do so while showing off her considerable Terpsichorean skills. The New York Times profile mentions that she travels with 20-30 pairs of shoes. Presumably some of those are dancing shoes. Check out the moves:
The DVD of this production of Giulio Cesare is seriously awesome. David McVicar's staging is different but it works. The cast, headed by the underappreciated Sarah Connolly, is first-rate. And the music is some of Handel's finest, ranging from joyous (like the number above) to pathos to downright pull-out-your-guts despair. Check out McVicar's commentary regarding "popular" music on Disk three - he nails it.
