From Estonia:
Väikeste Lõõtspillide Ühing (Little Accordion Orchestra). Great "party band" and reminds me an awful lot of the East Coast stuff from Canada. Some of my fave memories of Estonia. They like to drink, and this is the perfect band for it.
You can listen to their entire catalog on their website
