Big Band Madonna at the Ace Hotel (slide show)

Each month, Big Band Hot 100 brings big-band (duh) versions of today's pop hits to the Ace Hotel. The show—presided over by musical funny guy Ben Lerman and his 12-piece Titanics orchestra—always features a cavalcade of downtown stars; this week's all-Madonna edition had the likes of Amber Martin, Justin Vivian Bond, Eliot Glazer and plenty more taking on the Material Girl's many hits. Mark you calendars: The next Big Band Hot 100 is October 22. For more information, go to bigbandhot100.com.
