Nuit Blanche

Nuit Blanche is Paris' city-sponsored, all-night party/public art exhibit/random celebration, which falls on the last Saturday of every October.  It was started by Mayor Bertrand Delanoe in 2002 and has continued ever since, which is pretty cool considering he got stabbed at the first one.  These images were filmed at last year's in the Grand Palais.  The song is Will the Night, by Low, from the album Songs for a Dead Pilot.
