Angèle Dubeau & La Pietà's music video for "Les Beautés du diable" from their 2003 album Infernal Violins.
This particular piece, composed by François Dompierre, was written for La Pietà.
Although critically praised, I believe they may be the most under-appreciated gem in today's classical music industry. And having met Angele and some of the current performers, they are very gracious and kind as well!
