Nicole Renaud and her Lincordian

I was a this party on saturday. There were performances all night long. Suddenly, as an apparition, this frail woman walked in. She was wearing a long dress lit in blue and was carrying a transparent and luminous accordeon. Her voice and tunes just brought everyone to a hold.
I couldn't find anything good on Youtube, only the video below, but I do have this picture, and this is the link to her website.
