I realize I haven’t posted nearly enough accordion music lately and some readers will be disappointed. I’ll try to make it up to you with a Saturday morning Daily Dose.
Here’s a fellow named Sean Folsom playing a 3-row chromatic button accordion from 1900.
Now let’s go to Quebec and hear Denis Pépin…The Contradiction Reel
And…Gaston Nolet
27th Street 
For music I’ll take the reel- can anybody not like those but for performance it’s Nolet.
The other fellow, Sean Folsom, is best known as a piper and a master reed maker.
