Perhaps one of the more beautiful accordion videos on YouTube, even with the sub-pristine recording quality. Below is Dominique Rivière playing a Frédéric Paris tune, "Le Canal en Octobre," from Paris' CD Rue de l'Oiseau.
Rivière is playing a chromatic button accordion, different from the type I play. It's unisonorous, meaning that you get the same pitch on a button whether you're pushing or pulling the bellows. This is as opposed to bisonorous, typical of diatonic accordions like mine, where you get a different pitch depending on the bellows direction.* Rivière is a versatile musician, with his finger-style guitar and bouzouki work being just as intriguing as his accordion playing.
*Trust me, accordion geeks found those two previous sentences very meaningful.
